| Popis: | Relatively thick (in the range of 50 μm) electrochemically grown polyaniline films, with and without incorporated platinum microparticles, have been characterized by means of ac impedance measurements. In particular, resistance changes for both kinds of films were followed in situ (in 1 M aqueous H 2 SO 4 solution) as a function of potential. Rather unexpectedly, the rate of redos conversion of such polyaniline films is found to increase significantly in the presence of less than 100 μg cm -1 of electrodeposited metal particles dispersed inside the polymer layer |
