Erasable Optical Information Storage in the Polyanilines

Abstract

The polyaniline family of polymers exhibits properties that allow for the storage of optical information Photoexcitation of several forms of polyaniline results in long-lived changes in the absorption spectra, associated with trapped charged defect states. These new absorptions exhibit long lifetimes at low temperature (below -250 K), with erasure occurring upon warming the sample. Use in eraseble optical information storage devices and related technologies is discussed.
