Catalytic activity of V2O5 on aniline polymerization and the study of structural properties of poly(aniline)/V2O5 nano composite

摘要

It is a novel approach to the synthesize Poly(aniline) / V2O5 nano composite by free radical polymerization method under different experimental conditions such as variation in time, temperature and concentration of aniline and initiator. It was indicated that V2O5 itself could catalyze the oxidative polymerization of aniline. This can be attributed to the internal doping effect, which introduced flexibility to the rigid PANI backbone. TGA counseled the thermal stability of PANI. Through FTIR study, the structure of PANI was established. Comparison of polymerized aniline composite with two different initiators was done.
