Synthesis and characterization of PBZ/V2O5 composite materials

The composite materials of PBZ/V2O5 were synthesized by using emulsion polymerization at different molar ratio of PBZ to V2O5. FTIR, X-ray diffraction patterns, SEM and TEM measurement, TG analysis, cyclic voltammetry were used to characterize the samples. The result showed that: The morphology of PBZ/V2O5 composite materials changed from short micro-rods to long and thin micro fibers. Adding V2O5 was useful to increasing the crystallinity, thermal stability and electrochemical activity of PBZ. When the molar ratio of PBZ to V2O5 was 10:1 and 15:1, the degree of polymerization and the embedded level were all better than other samples, the electrochemical activities and the thermal stabilities of composite materials were the best when the molar ratio was 10:1.
