Abstract Catalytic graphitization of polyarylacetylene resin was studied with the assistance of different kinds of catalysts. The effects of Fe2O3 and carbonized temperature on PAA graphitization were investigated The structure and morphology of PAA resin and graphitized products were characterized by XRD, Raman, SEM and HRTEM. The results show that Fe2O3 was reduced to iron during calcining, which accelerated the graphitization of polyarylacetylene resin. The graphitic structure was formed with the increases of both Fe2O3amount and heat treated temperature, and the degree of graphitization was 92.3%. The graphitized product was composed of the graphitic carbon, the iron nanoparticles and the amorphous carbon. The iron nanoparticles were encapsulated by the graphitic layers. The graphitized nano-ribbon extended throughout the amorphous carbon matrix and interconnected each other to form a graphitized nano-ribbon network.
