Conductivity Changes of Polyacetylene Exposed to SO2

Abstract

The conductivity change of polyacetylene foils under exposure with different pressures of sulfur dioxide vapor was measured as a function of time. Adsorption and diffusion are the rate determining steps for the increase of the conductivity. A simple mathematical description of the two processes yields agreement with experiment.
