摘要：

Anomalies in the temperature dependence of the conductivity of BF4- doped polypyrrole were observed in cyclic measurements at temperatures between 250 K and 310 K. The anomalies were accompanied by endothermic effects in differential scanning calorimetry and are interpreted as being due to conformational changes (creation and disappearance of conformational defects) in the polymer chains. The conformational defects are supposed to influence the energy and the concentration of bipolarons and, consequently, the transport in the polymer.
