摘要：

Polyaniline highly doped with acrylamido-2-methyl-1-propanesulphonic (PANI-AMPSA) and camphorsulfonic (PANI-CSA) acids have been studied at X- (9.5 GHz) and K- (37.5 GHz) bands EPR. Localized Curie-like and mobile Pauli-like spin charge carriers are stabilized in amorphous and crystalline regions of the samples. AC conductivity contributed from these paramagnetic centers was determined. It was shown that, in contrast with PANI-AMPSA, PANI-CSA with higher both d.c. and a.c. conductivity is a more ordered metal with more rigid and planar polymer chains.
