Thermal characteristics of polymer composites are similar to the properties of metal, with the mechanical properties being similar to plastics. Thermal conductivity of a polymer composite depends on geometry of the filler, and interaction and dispersal of the filler within the polymer matrix. In this study, thermal conductivity of copper and Al₂O₃ filled polymer composites were investigated. A Thermal Constant Analyzer was used to measure thermal conductivity of the ...

To improve the thermal conductivity of polymeric matrixes, conducting fillers were added to polymers, specifically graphite, having good thermal conductivity and dispersibility. Exfoliated graphite (EG) and graphite nanoplatelets (GNP) are excellent alternatives to metal and carbon as conductive polymer composites, through solution mixing and melt blending techniques. Thermal conductivity of composites was measured by a thermal analyzer, using the transient plane source (TPS) method. Solid-state shear milling treated composites showed ...

Graphene is a 2D single layer of carbon atoms, superior to graphite in mechanical properties and thermal conductivity. Polymer/graphene composites can be fabricated using several techniques, however this study analyzed a solid state in situ method for the creation of polyamide-6 (PA6)/graphene composites. Thermal conductivity was measured using a Thermal Constant Analyzer by transient plane source method. Thermal conductivity of PA6-graphene composites increased with the increase of ...

Nano-sized materials with large aspect ratios are found to be effective as second fillers for the formation of 3D thermally conductive networks in polymer composites. In this study, multi-walled carbon nanotube (MWCNT) was incorporated as second filler for polymer composites. A thermal analyzer was used to measure thermal conductivity of composites at room temperature. Expanded graphite and MWCNT, as fillers, effectively enhanced thermal conductivity of the composites due to its ...

One way to improve thermal and electrical conductivity of conventional polymers is by combining polymer matrices with highly conductive fillers. This study involves an analysis of electrical and thermal conductivities of nonirradiated and irradiated samples of ethylene vinyl acetate 18 (EVA18) containing expanded graphite (EG) or SDS-EG. Thermal conductivity measurements were at room temperature. An increase in thermal conductivity was found with increasing filler content in all investigated samples, due to ...
