Abstract

Polyanniline films containing TiO2 particles have been shown to be an effective medium for photo-induced electrochromism. This effect has been utilized to achieve image storage and writing with laser light in the polyaniline films. The production of the films, their applications, and directions for future work, including the incorporation of semiconductor particles into the conducting polymer, are discussed.
