In this study, graphene nanoplatelets (GNP) and multi-walled carbon nanotube fillers (MWCNT) were simultaneously added to a polycarbonate matrix, in an attempt to improve thermal conductivity. Thermal conductivities of the composites were measured at room temperature. Results show that MWCNTs can improve thermal conductivity by filling gaps between GNPs. Additionally, a small amount of well dispersed MWCNTs increased thermal conductivity by 23% compared to composites containing only GNPs....
It was found that the thermal conductivity of composite materials is enhanced by the simultaneous incorporation of dispersed pitch-based carbon fibers (PCFs) and graphene nanoplatelets (GNPs). This study investigated methods for optimizing thermal conductivity. A thermal conductivity analyzer was used to compare thermal conductivity of composites filled with PCF and/or GNP. Results show the values of thermal conductivity increased as the filler content increased, and a greater synergistic improvement ...
