Polymer composites have been studied in many fields because of their advantages such as light weight, chemical resistance and low cost, and various fillers are used according to purpose. Carbon-based polymer composites incorporating carbon fillers such as graphene and CNT have been studied because they can complement the low thermal conductivity of polymers. Among them, the synergistic effect of the thermal conductivity of the composite mixed with different kinds of carbon nanofillers was also reported. In this case, 3D network in composites formed by two-dimensional Graphene based 1-dimensional CNT bridge effect has been reported as a main factor of them. However, many studies have been conducted at low contents (less than 20 wt%). In this study, to investigate the synergistic effect of thermal conductivity in the high filler content (30 ~ 50 wt%), we propose a manufacture process of polymer composites containing both GNP and CNT simultaneously and analyzed the thermal conductivity. |
