Preparation and characterization of transparent and conductive PANI/ATO hybrid films

New organic-inorganic hybrid films with relative high conductivity and good optical transmittance were synthesized by polymerization of antimony-doped tin oxide in the presence of polyaniline via a sol-gel method. Visible light transmittance of the obtained film was over 80%, and its conductivity reached 1 similar to 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 temperature of 300 degrees C, water content R-w 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.
