The purpose of this paper is to study the effects of multi-walled carbon nanotubes (MWCNTs) loading on the thermal conductivity of nanocomposites.

In this paper, the polymer nanocomposite of MWCNT nanoparticles incorporated with PLA and LNR as compatibilizer were prepared via melt blending method.

The result has shown that the sample with 3.5 wt.% of MWCNT content provided higher thermal conductivity which is believed to be the optimum loading that formed the suitable percolated network for phonon conduction facilitation because of better dispersion in the PLA/LNR matrix as confirmed by SEM micrograph.

Thermal conductivity of polylactic acid (PLA)/liquid natural rubber (LNR) matrix improved with MWCNT.

This paper examines the enhancement in the properties of thermoplastic elastomer (TPE) reinforced by graphene nanoplates (GNPs). TPE is a blend of polypropylene (PP), natural rubber (NR) and liquid natural rubber (LNR), which is used as a compatibiliser at a percentage of volume ratio 70:10:20, respectively. Using TPE as the host matrix, TPE/GNPs nanocomposites are processed, and the mechanical, electrical and structural properties are characterised. The results extracted from the tensile and the impact tests showed that the tensile strength, Young’s modulus and the impact strength of the nanocomposites also increased as the filler loading increased until an optimum value of filler loading was reached. Based on the experimental results, GNPs strongly affected the electrical conductivity due to disruption of the GNPs percolated network. It is believed that the high aspect ratio of GNPs is a critical issue concerning the constitution of a special interface region between the GNPs and TPE matrix and the high performance of the composites.

Three types of fillers were incorporated in the thermoplastic natural rubber by melt blending process. They are NiZn ferrite, multiwalled carbon nanotubes, and hybrid NiZn ferrite/multiwalled carbon nanotubes followed by weight ratio of 1:1. Their magnetic properties and microwave absorbing properties were investigated. The ball-milled techniques, resulted good filler dispersion in hybrid nanocomposite, proven by the matching saturation magnetization experimental values with the theory calculation. It was found that the magnetic property strongly depends on the amount of magnetic particles in the nanocomposites. The mixing of two different types of filler (multiwalled carbon nanotubes and NiZn ferrite) showed an enhancement of the microwave properties at lower filler loading.
