摘要

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 TiO_2 and Al_2O_3, the conductivity increased after heat treatment at 85 deg. C and reached l7 Scm~-1. The conductivity of the film depended on the kinds and amounts of metal oxides and the temperature of heat treatment.
