Preparation of conducting film composed of polyaniline and metal oxide by sol-gel method

Extract
Conducting thin films were prepared by entrapping water-suspended polyaniline into a silica matrix by a sol-gel route. Without metal oxide, the conductivity of the film decreased after heat treatment. However, in the presence of metal oxides such as TiO2 and Al2O3, the conductivity increased after heat treatment at 85 °C and reached 17 Scm−1 The conductivity of the film depended on the kinds and amounts of metal oxides and the temperature of heat treatment.
