DC Electrical Anisotropy of Stretchoriented Polyacetylene: Doping and Temperature Dependence
The DC electrical conductivity of stretch-oriented “new” polyacetylene (prepared by the sol vent-free method, “cummene-polyacetylene” according to Akagi et al.) has been measured for various concentrations of iodine, AsF5, and FeCl3 doping in the temperature range 300 K>T>5 K. The electrical anisotropy (ratio of conductivity parallel and perpendicular to the draw direction) has been found to increase rapidly with the doping concentration for 0<y<1% and slowly above (where y is the doping concentration according to (CH+y · yI 3 - )x). Only a slight temperature dependence of the anisotropy has been found.
