Carbon nanotubes (CNTs) have extremely high thermal conductivity and can raise the thermal conductivity of a polymer matrix when used as an additive. Previous research has shown that random CNT orientation in polymer matrices gives a much lower thermal conductivity value than a specific alignment direction. This project tested the thermal conductivity of oils and polymers. Results were encouraging, with the thermal conductivity of the composites increasing linearly with the ...
The goal of this study was to determine how adding CdS nanoparticles to two polymer blends (PS/PVC and PS/PMMA) affects their thermal conductivities. Also, the effect of increasing the wt% of both PVC and PMMA in their respective blends was investigated. The thermal conductivity of the samples was determined through a transient plane method. The thermal conductivity of both polymer blends increased with the addition of CdS nanoparticles. ...
Graphite papers can enhance mechanical properties while lowering electrical properties, however, to generate conducting membranes, the chemical and thermal characteristics of the papers require further reduction. In this study, mercaptobenzene (MB) functionalized graphite and epoxy-based hybrid membranes were prepared and analyzed. A thermal analyzer measured the thermal conductivity of the samples using the transient plane source (TPS) method. Results showed that the powder-pressed pellets made of graphite-MB-gold nanoparticles (AuNPs) had ...
The aim of this study was to fabricate transparent polymers with high thermal conductivities for applications in electronic packaging. Characteristics of the inorganic filler, calcium fluoride (CaF2), and the polymer matrix were examined, and thermal conductivity was measured using a thermal analyzer based on the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with CaF2 content. This study was the first to report ...
Silicone materials have high electrical and thermal insulation properties that are useful for engineering applications. In this study, vapour grown carbon nanofibers (VGCNF) were produced by two different methods and were added to silicone rubber to improve conductivity. A thermal constant analyser measured the thermal conductivities of the silicone and its composites using the transient plane source (TPS) method. Results showed that thermal conductivities of the roll-mill produced VGCNF/silicone ...
