Abstract

Purpose

This paper aims to investigate the prepared modified alkyd and poly(ester-amide) (PEA) resins as antimicrobial and insecticide binders for surface coating applications.

Design/methodology/approach

Salicylic diethanolamine and 4-(N, N-dimethylamino) benzylidene glutamic acid were prepared and used as new sources of polyol and dibasic acid for PEA and alkyd resins, then confirmed by: acid value, FT-IR and 1H-NMR. The coating performance of the resins was determined using measurements of physico-mechanical properties. The biological and insecticide activities of the prepared resins were investigated.

Findings

The tests carried out revealed that the modified PEA and alkyd enhanced both phyisco-mechanical and chemical properties in addition to the biological and insecticide activities. The results of this paper illustrate that the introduction of salicylic diethanolamine and 4-(N, N-dimethylamino) benzylidene glutamic acid within the resin structure improved the film performance and enhanced the antimicrobial activity performance of PEA and alkyd resins.

Research limitations/implications

The modified alkyd and PEA organic resins can be used as biocidal binders when incorporated into paint formulations for multiple surface applications, especially those that are exposed to several organisms.

Originality/value

Modified alkyd and PEA resins based on newly synthesized modifiers have a significant potential to be promising in the production and development of antimicrobial and insecticide paints, allowing them to function to restrict the spread of insects and microbial infection.

Abstract

Purpose

Malaysian small and medium-sized enterprises (SMEs) are critical for economic development and meeting the sustainable development goals (SDGs); however, many struggle to survive in the long term. So, this study aims to present a model for sustainable growth that bridges the gap between desired growth and managerial competencies. By configuring university helix-induced crowdfunding and opportunity recognition competencies with industry helix-driven innovation, the study encourages a quadruple bottom line (QBL) strategy, helping SMEs attain competitiveness for sustainable growth.

Design/methodology/approach

This pilot study used a sequential mixed methods design and adhered to the pragmatic research paradigm. A survey of 52 SCORE-listed manufacturers yielded quantitative data, complemented by qualitative interviews with 7 SME decision makers. This study used NVivo 10 and SmartPLS 4.0 for the necessary analysis. In addition, an effective triangulation strategy has been implemented to explain causation among selected variables.

Findings

The findings show that opportunity recognition and crowdfunding are positively associated with SMEs’ ability to grow in a sustainable manner and that exploitative and explorative innovation also mediate those relationships. The qualitative part highlighted key insights for successfully applying this model in Malaysian SMEs. The interview results also suggest that corporate spirituality might help SMEs adopt sustainability-focused practices.

Research limitations/implications

More research is required regarding both the methods and results of this pilot study. Although conducting a pilot study increases the likelihood of success in the main study, it does not ensure it.

Practical implications

This study equips Malaysian SMEs with a roadmap for achieving sustainable growth. The obtained findings indicate that Malaysian SMEs that develop strong crowdfunding and opportunity recognition competencies are more likely to achieve innovation-focused long-term survival. In addition, incorporating corporate spirituality can enhance their economic, social and environmental performance.

Social implications

By supporting more innovation in SMEs, which can improve sustainability-oriented successes and support a healthy economic system, these findings may have a beneficial social change impact. The concept may also act as the foundation for SMEs’ promotion of the SDGs.

Originality/value

The study uniquely offers a holistic growth model for Malaysian SMEs founded on the helix-QBL understanding that explains a firm’s sustainability-focused competitive advantage.

Abstract

Purpose

This study aims to synthesize new cyclodiphosph(V)azane derivatives, 2,2,4,4-tetrachloro-1,3-di-[o-nitriyl]-2,4-di-[N-(pyrimidin-2-yl)benzenesulfonamide]-1,3,2,4- diazadiphosphetidine(H2L) ligand and their Fe(III) and Ag(I) metal complexes as insecticides for protective coatings.

Design/methodology/approach

The substitutes of cyclodiphosph(V)azane sulfonomide and their Fe(III), Ag(I) metal complexes were prepared and confirmed by a combination of elemental analyses, mass spectra, conductivity measurement-vis, FTIR, 1H,13C-NMR TGA, XRD and Docking investigation of the ligand and some complexes to verify their drug ability. The prepared compounds have been incorporated with a polyurethane (PU) coating formula. Gloss, scratch resistance, flexibility and adhesion are some of the coating attributes investigated; mechanical capabilities include impact resistance and shore hardness and physicochemical properties such as chemical resistance of coated PU samples are also investigated.

Findings

The results of the experiments revealed that all PU coatings based on the prepared compounds had good scratch resistance which varied from >1.8 to >2.2 kg. Gloss value varied from 85 to 95 and impact resistance from 1.4 to 2.0 (J), whereas the authors noticed that there was no effect of the prepared compounds in the flexibility and adhesion test. These PU coatings have excellent chemical resistance except the alkali resistance. Insecticide activities of the prepared compounds are promising for resistance to these insects. It was noticed that, metal complex > incorporated PU with Fe (III) metal complex > incorporated PU with ligand.

Originality/value

Insecticide paints based on cyclodiphosph(V)azane sulfonamide and their Fe(III), Ag(I) metal complexes as insecticide agents are novel.

Abstract

Purpose

Small and medium-sized firms (SMEs) are typically reported to have a limited interest in broader societal concerns across the world. As a result, the purpose of this study is to develop a model of SME’s strategic philanthropic performance in light of the societal reactions to the COVID-19 issue, particularly in terms of the intervention of corporate spirituality and the solid regulatory motive behind these.

Design/methodology/approach

A systematic mixed review analysis has been executed to analyze the strategic philanthropic performance configuration triggered by the recent COVID-19 crisis, in which over 369 publications are read and reviewed by the authors. It has also established the reliability and validity of literature analysis. Also besides, a short form of qualitative investigation has been used to support the direction of the study.

Findings

Through regulatory adjustments, the study's findings effectively developed a strategic philanthropic performance configuration for SMEs. In this case, the strategic philanthropic convergence of corporate giving, corporate volunteering, corporate foundation and food bank has the potential to help SMEs thrive in the long run. The study also discovers that corporate spirituality might potentially mediate between appropriate regulations and strategic philanthropic performance of SMEs in the context of a supportive external environment.

Research limitations/implications

Prior empirical attempts are subsequently required to inquiry about the proposed conceptualization from different perspectives.

Practical implications

The decision-makers of SMEs, with the efficient implementation of the proposed outline, will use the understanding given for their required actions to develop the competitive advantage in terms of social concerns. On this note, the outcomes of the study can also enhance business differentiation and competitiveness. It can also serve as a strategic guideline for firms to develop organizational values for long-term survival.

Social implications

In the COVID-19 reality, SMEs will contribute to the concerns through philanthropy activities that are better suited for both enhanced social good and greater corporate advantages. The idea can also serve as a basis for SMEs to accomplish the Sustainable Development Goals (SDGs).

Originality/value

To the best of the authors' knowledge, this is the first research that conceptualizes the influence of government regulation on the strategic philanthropic performance of SMEs while taking corporate spirituality into account in order to survive the COVID-19 crisis.

Abstract

Purpose

The purpose of this paper is devoted to application of the emulsion polymer of poly(methyl methacrylate-co-butyl acrylate) prepared with in situ nano-silica as a novel tanning agent of hide to partly or totally replace chrome salt and to improve physical, thermal and mechanical properties of the tanned leather and to reduce the environmental impact of chrome tanning effluent.

Design/methodology/approach

Polymer/nano-silica hybrid emulsions were prepared via in situ seed emulsion polymerisation. The prepared polymers were characterised for solid content, molecular weight, viscosity, drying time, minimum film-forming temperature (MFFT) and microstructures (via transmission electron microscopy). The mechanical, thermal and surface morphological (by scanning electron microscope) properties of the treated samples were also investigated. The influences of the increase in the content of organic nano-silica on the properties of the tanned leather are discussed.

Findings

It was found that the viscosity, the particle size and the solid content of the prepared polymers increased as the content of the nano-silica increased while gloss and drying time of the resulting polymer film decreased. Tanning buffalo hide by Polymer F (containing a high content of nano-silica) gave desirable properties in terms of tensile strength, thermal stability and shrinkage temperature.

Research limitations/implications

This paper discusses the preparation and the characterisation of emulsion polymers with in situ nano-silica and their application in tanning process to enhance and improve the leather quality, as well as reduce the use of chrome tanning materials and consequently chrome tanning waste.

Practical implications

The tanned leather showed an improvement of physico-mechanical properties and enhancement of thermal stability. Furthermore, the tanned leather has uniform colour, softness and firmness of grain. All these promising results provide evidence to support the applicability of the prepared co-polymer/nano-silica emulsions as an efficient tanning agent that also provides lubricating properties for leather.

Originality/value

Since May 2015, REACH Annex XVII restricts Cr(VI) in leather articles or leather parts of articles that come into contact with skin to a concentration of less than 3 mg/kg. Cases of discovery of Cr(VI) in leather papers have been reported by the European rapid alert system on dangerous consumer products (RAPEX). The emulsion poly (methyl methacrylate-co-butyl acrylate) with in situ nano-silica that has been developed via the study reported in this paper is one of the better technologies for the reduction of chromium ratio used in tanning industry.

Abstract

Purpose

The purpose of this study is to develop a new protective coating formulation for industrial use, using benzodiazepine derivatives as double function additives.

Design/methodology/approach

Benzodiazepine’s derivatives of types (3–5) were prepared and confirmed by infrared, Mass, 1H-Proton nuclear magnetic resonance (NMR) and 13C NMR spectra. The synthesized compound was physically incorporated in the alkyd paint formulation by pebble mill grinding until all particulates are smaller than 20 ums. The prepared coatings were applied by air spray on steel panels. The physical, mechanical characteristics, corrosion resistance and antimicrobial test of the prepared coatings were studied to evaluate the prepared compounds drawbacks.

Findings

The results of the mechanical and physical properties of the paint formulation revealed that the paint formulation incorporating benzodiazepines derivatives 3–5 performed best and improved corrosion-resistance and antibacterial activity tests.

Research limitations/implications

In alkyd paint, heterocyclic compounds are the most used antibacterial additives. Other functionalities of these compounds, such as corrosion inhibitors, might be studied to see if they are suited for these applications.

Practical implications

Because of the activity of various benzodiazepine derivatives, which may be attributable to the presence of some function groups such as sulfonamide aromatic amino NH2 group, and elements such as Sulphur, Nitrogen, Chlorine, in its chemical structure. As a result, paint compositions including these compounds as additives can be used as dual-purpose paint and for a variety of industrial applications.

Originality/value

The research demonstrates how a low-cost paint composition based on synthesized benzodiazepine derivatives 3–5 may be used as a dual-function paint for industrial use.

Abstract

Purpose

The purpose of this paper is to prepare, characterise and evaluate nano-emulsions of copolymers of various compositions as eco-friendly binders for flexographic ink industry.

Design/methodology/approach

Various nano-emulsions of copolymers were prepared using styrene (St), butyl acrylate (BuAc), acrylic acid (AA) and acrylamide (AAm) monomers by means of a conventional seeded emulsion polymerisation technique, using K2S2O8 as the initiator. The characterisation of the prepared emulsions was performed using Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), gel permeation chromatography (GPC) and transmission electron microscopy (TEM). A selection of copolymers was formulated with pigments and additional ingredients, as water-based flexographic inks. The inks were characterised for their viscosity, pH, degree of dispersion, water resistance and colour density.

Findings

It was found that the low viscosity of the prepared copolymers may reduce the film thickness of the flexographic inks and may also increase the spreading of the ink on the surface. As a result, stable modified polyacrylate-based latex with improved physico-mechanical properties were obtained. The prepared latexes were showed improving and enhancing in water resistance; gloss values, and the print density that ranged from 2.06 to 2.51 and the maximum gloss values (39 and 48) were also obtained. Also, these binders provide excellent adhesion properties for both the pigment particles and the base paper.

Practical implications

This study focuses on the preparation of new water-based copolymer nanoparticles and their use as eco-friendly binders for flexographic ink industry.

Social implications

The ink formulations developed could find use in industrial-scale printing.

Originality/value

Eco-friendly environment ink formulations for printing on paper substrates are novel.

Abstract

Purpose

For Bangladeshi small and medium enterprises (SMEs), the COVID-19 economic shock is remarkable in both its complexity and intensity. SMEs need systemic inspiration to solve the crisis, aligned with a moral and authentic approach that serves both the leader and the follower’s interests. This study aims to conceptualize the innovation-focused success method of SMEs before and after the pandemic to manage the crisis by establishing spiritual leadership based on Islamic perspectives.

Design/methodology/approach

To discuss the impact of spiritual leadership on innovation-focused SME performance configuration through the lens of a crisis, a comprehensive literature study has been carried out in which over 360 articles are read and reviewed by the authors. It has also established the reliability and validity of literature analysis. Also, a qualitative investigation has been used to support the direction of the study.

Findings

For a subsequent process of scientific deployment and evaluation of its execution, a new applied strategic innovation-focused SME success configuration through spiritual leadership development is made available. The primary value of this paradigm is the potential to calculate and treat the aspects of spiritual leadership obtained from Islamic ideas.

Research limitations/implications

Prior analytical or empirical attempts from multiple viewpoints are subsequently needed to inquire about the proposed conceptualization.

Practical implications

Among the realistic consequences of this analysis is that while a number of leadership paradigms have been embraced by a broad body of leadership studies, the findings indicate that this paper should pay heed to the influential spiritual style of leadership, taking into account Islamic perspectives on the context of crisis. Therefore, Bangladeshi SMEs need to develop and run leadership training programs focused on the Islamic viewpoint of spirituality to encourage the actions of leaders during and after crises.

Social implications

The legal and moral values of the society would ultimately be upgraded from this conceptualization. Moreover, less corruption in corporate activities would improve the economic prosperity of a nation. It would also contribute to the cross-cultural portrayal of the positive picture of Islam.

Originality/value

This holistic conceptualization describes the mediating role of strategic innovation practices based on theoretical foundations, which have seldom been done in previous research, between the Islamic model of spiritual leadership and SME success during and after a crisis.

Abstract

Purpose

SMEs that manage more sustainability focused initiatives into their core business strategy can possibly benefit from lower expenses, reduced threats and new business opportunities, but in Malaysia most of the SMEs are still far off in terms of adapting to a sustainable business growth outline from a holistic point of view. Hence, this study aims to serve deeper understanding about a strategic innovation focused sustainable growth model on basis of multidisciplinary QBL-QHIM theoretical perspectives where strategic innovation practices intervene in between desired growth and government support (regulations).

Design/methodology/approach

This conceptual investigation embraces a newly emerged concern of sustainable business growth in SMEs, considering ranges of literature reviews from the disciplines of management and entrepreneurship. The study also systematically explores the concepts of regulations, strategic innovation practices on basis of QBL and QHIM theories to adjust the sustainable business growth model from a holistic angle.

Findings

The outcomes show that multidisciplinary QBL-QHIM conjunction within the interrelationships of the selected constructs holds the potential for innovation focused business growth in a more sustainable, comprehensive and holistic manner. The study also detects that exploitative-explorative innovation practices can possibly mediate in between suitable regulations and sustainable business growth of SMEs, considering supportive external environment.

Research limitations/implications

Researches are encouraged to test the proposed model.

Practical implications

The study indicates a conceptual configuration for policy makers as well as entrepreneurs to ensure sustainable business growth for SMEs. The outcomes of the study also provide useful direction on decision-making process of owner or manager considering social, economic, environmental and spiritual aspects of daily operations.

Social implications

The conceptual model may possibly able to generate more social values, considering a holistic angle into business activities.

Originality/value

The conceptualization is a unique attempt, considering developing regions to extend the current understanding of strategic innovation focused sustainable growth process of SMEs from a holistic angle.
