摘要：
Spin dynamics has been investigated by NMR techniques in highly conducting polyaniline (PANI-CSA) aged at 135 degrees C in room atmosphere for times going from 0 to 14 days. Proton nuclear relaxation times have been measured as a function of frequency and temperature. Data are analyzed in the frame of an heterogeneous disorder with metallic regions connected by poorly conducting disordered chains. Aging acts as a corrosion process of the metallic parts without affecting the dynamics in amorphous zones.
