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

Abstract

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.

“…The thermal properties of PANI can be increased by making nanocomposites with various metal or metaloxide nanoparticles because the added nano material can occupy the space between the polymer chains as a filler. Poly(aniline)s were made nanocomposite with CuO [17], ZrO2 [18], kaolinite [19], MnO2 [20], CdS [21], TiO2 [22], V2O5 [23], As2O3 [24], Sb2O3 [25] and ZnO [26]. By this way the thermal stability of PANI was increased.…”
