摘要：

Polyvinylpyrrolidone/polyaniline (PVP/PANI) with additives (TiO2, ZnO, NaCl and Na2SO4) was synthesized. To spread the electric and photoelectric applications of PVP/PANI, its photodegradation under UV irradiation was studied by Fourier transform infrared spectroscopy, diffuse reflectance spectroscopy, water uptake and scanning electron microscopy. Results show that ZnO, TiO2 and NaCl accelerate the photodegradation, respectively, but Na2SO4 stabilized PVP/PANI. The degradation rate of PVP/PANI/tert-butyl alcohol and PVP/PANI/ascorbic acid proved the radical role. Water uptake results show that the power of interactions is in this order: PVP/PANI/Na2SO4 > PVP/PANI/TiO2 > PVP/PANI/ZnO > PVP/PANI > PVP/PANI/NaCl > PVP/PANI/tert-butyl alcohol> PVP/PANI/ascorbic acid.
