Abstract
Polypyrroles electrochemically obtained at the same conditions and dif ferent density currents have been studied by ESR. We analyze the angul ar dependence of the ESR linewidths when rotating the sample in the ma gnetic field, and correlate it with the degree of ordering in the samp le. Electrical conductivity is higher for samples obtained at high den sity current, for which no ordering is observed. This suggests that am orphicity contributes positively to transport in polypyrroles.
