Abstract
The correlation between conductivity and ESR characteristics is invest igated in the case of aged polypyrrole samples. Polypyrrole powder was obtained by chemical oxidation at 3 degrees C with 1-naphthalen sulfo nic acid as doping species and then heated to 140 degrees C under eith er air or argon to accelerate the ageing process. Quantitative measure ments have been carried out as a function of heating time. ESR data ar e discussed and compared to those of conductivity measurements obtaine d in the same conditions.
