It has been found that thin polyaniline films doped with several zinc
salts in solutions at pH 5.5 become electroconductive and electroactiv
e in neutral aqueous electrolytes. Tile shape of the voltammetric char
acteristics depends on the initial state of the film. The effect of ''
secondary doping'' with m-cresol is observed for polyaniline complexes
with zinc salt of camphorsulfonic acid.
