透明PANI/ATO杂化导电薄膜的制备与表征

Preparation and Characterization of Transparent and Conductive PANI/ATO Hybrid Films

以聚苯胺和掺锑的氧化锡作为主要原料、采用溶胶-凝胶法制备了新型有机-无机杂化的透明导电薄膜,薄膜的可见光透过率为80%以上、电导率达到1￣10S·cm-1。着重研究了制备过程中热处理温度、引入水量以及浸涂液浓度对薄膜的结构、可见光透过率和电导率的影响。确定了薄膜的最佳工艺条件为:热处理温度为300℃、引入水量为Rw=12、浸涂液的浓度为114g·L-1。浸涂液的粘度可在长达25d的时间内保持稳定。

New organic-inorganic hybrid films with relative high conductivity synthesized by polymerization of antimony-doped tin oxide in the presence and good optical transmittance were of polyaniline v/a a sol-gel method. Visible light transmittance of the obtained film was over 80%, and its conductivity reached 1-10 S·cm^-1. The effects of heat treatment, water content and concentration of solutions on the structure, transmittance and conductivity of the hybrid films were investigated. The optimized preparation conditions are as follows： the heating tem- perature of 300℃, water content RW of 12 and the concentration of the solution being 114 g·L^-1. The viscosity of the dipping solution was almost unchanged during 25 days.
