摘要：

Conducting polypyrrole films with thickness of about 8-mu-m were prepared on platinum by continuous scanning in 0.1M pyrrole and 0.1M electrolyte (LiCl, LiBF4 or NaBF4). Scan-rates of 10, 20 and 50 mV/sec with scan-times of 30, 45 and 60 min were used. The potentiometric response of the films was tested over a range of anions. Films were found to be anion-sensitive but very non-selective. The influence of the doping cation was also investigated.
