High Thermal Conductive BBL/Graphene Nanocomposite System

Abstract

Electrical conductivity of graphene/poly(benzimidazobenzophenanthroline) (BBL) composites was evaluated. Both graphene oxides (GOs) and reduced GOs (rGOs) were found to be well dispersed in BBL; in situ thermal reduction of GO was possible due to the high thermal degradation temperature of BBL (>600 degrees C). Electrical conductivity of the GO/BBL composite increased by approximately 4 orders after annealing at 500 degrees C for 30 minutes. Chemically-reduced GOs were also applicable to the rGO/BBL nanocomposite system and the post-heat treatment of the GO/BBL composite was also effective to impart good electrical conductivity to BBL.
