摘要：

The dc-conductivity and thermoelectric power of electrochemically prepared polypyroles have been investigated in the temperature range between 300 K and 1. 3 K on unaged, aged (24-120 days at 80 degree C in air) and chemically modified samples. The linear temperature dependence of the thermopower of unaged polypyrroles demonstrates clearly the contribution of metallic regions to the electronic transport properties. The temperature dependence of the conductivity of the polypyrroles investigated corresponds to that predicted by the variable range hopping model.
