Abstract
Purpose
The paper aims to study the effects of humidity on the electrical properties of copper phthalocyanine (CuPc) thin films deposited at different gravity conditions.
Design/methodology/approach
Surface-type samples were fabricated on glass substrates with preliminary-deposited copper electrodes. The CuPc solution was prepared in benzene. The thin films of CuPc were deposited on these substrates at diverse gravity conditions by drop-casting and centrifugation at 1 × g and 70 × g, respectively. Impedance and capacitance of the fabricated devices were measured against the different relative humidity ranging from 32 to 98 per cent.
Findings
The impedance and the capacitance of the CuPc film were found to be dependent on the ambient humidity levels (32-98 per cent) and the gravity conditions (1 × g and 70 × g) opted during the fabrication process.
Research limitations/implications
The centrifugation technique can potentially be used in the instrumentation industry for the fabrication of humidity sensors.
Practical implications
The results of the investigations can potentially be used in the instrumentation and optoelectronics industry for the fabrication of humidity sensors.
Originality/value
CuPc films were deposited from a solution in benzene using drop-casting and centrifugation. The electrical properties of the films were found to be dependent on film fabrication conditions and ambient humidity levels. Growth-dependent electrical properties of the CuPc films can be explained by considering their structure.

Abstract
The sources and platforms utilized for environmental communication have been significantly expanded by the emergence of social media. The validity, form, and content of environmental communication processes are particularly radical departures from conventional media, making personal green blogs important of study as areas of everyday culture politics where people make understanding of environmental challenges. There is currently a lack of research on how social media might encourage green behaviours. This research reveals the impact of social media use and green blogging on green purchasing behaviour, which is supported by the social learning theory. Present study shows that social media use and green blogging have a substantial positive connection, drawing on a sample of 580 respondents from Pakistan examined using structural equation modelling. Both notions have a considerable impact on consumers' intentions to make green purchases, and social media trust plays a moderating role in this relationship. Furthermore, social media trust considerably modifies the connections between green blogging and social media use that is related to green behaviour. The current study is novel and offers important information to understand how social media might promote eco-friendly habits and behaviour.
