Electrical conductivity of graphenepolybenzimidazobenzophenanthroline 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 GOBBL composite increased by approximately 4 orders after annealing at 500 degrees C for 30 minutes. Chemically-reduced GOs were also applicable to the rGOBBL nanocomposite system and the post-heat treatment of the GOBBL composite was also effective to impart good electrical conductivity to BBL.
