were studied by investigating the synergy of both fillers and the dimensions of the conducting filler network.The SCF was more effective in enhancing the thermal conductivity of PDMS than wCNT due to its larger aspect ratio and more homogeneous dispersion, which facilitated the formation of a conti...
Carbon black filled polydimethylsiloxane (PDMS) was considered as a prospective bipolar plate material candidate for a fuel cell. In this perspective, thermal conductivity and stability of the composites were investigated. Samples with filler weight fractions from 10% to 25% were prepared. The Therma...
Thermal diffusivity, heat capacity, and density of polyvinyl chloride/polycaprolactone (PVC/PCL) blends were measured by the laser flash method, DSC, and pycnometry, respectively. The thermal conductivity of the PVC/PCL blends was determined from the results. The miscibility of the blend and cryst...
The highest k (TG), which was 23 times greater than the original k (PDMS), appeared in a ZnO-containing double-filler grease (=3.52 W/mK). The prediction for the maximum attainable thermal conductivity was preliminarily supported. 展开 ...

As a material possessing extremely high thermal conductivity, graphene has been considered as the ultimate filler for fabrication of highly thermally conductive polymer composites. In the past decade, graphene and its derivatives were demonstrated in many studies to be very effective in enhancing the th...
