Enhancement of electrical conductivity of poly(p-phenylene) and polynaphthylene films by heat treatment

Electrical conductivity of poly(p-phenylene) and polynaphthylene films increases by many orders of magnitude by the heat treatment at temperatures between 400 and 1000 °C, which is interpreted in terms of the carbonization. A linear temperature dependence of thermoelectric power also supports this i...

Description
Summary:Electrical conductivity of poly(p-phenylene) and polynaphthylene films increases by many orders of magnitude by the heat treatment at temperatures between 400 and 1000 °C, which is interpreted in terms of the carbonization. A linear temperature dependence of thermoelectric power also supports this interpretation.
