The electrical and optical properties of poly (4-ethylidene-l, 3-cyclopentylene vinylene)

Abstract

The intrinsic viscosity, electrical conductivity and IR absorbance were measured for the sample of poly (4—ethylidene—1, 3—cyclopentylene vinylene). The sample is strongly oxidized in air. Under vacuum the activation energy is 1.38 eV at T > 377°K. The electrical conductivity of the annealed samples increases at low temperature and decreases at high temperature. The electrical conductivity of the samples which were exposed to air shows the metallic behaviour.
