Xw. Li et al., Study on electrocatalytic performance of polyaniline film electrode in polymerization of aniline monomer, CHIN J CATA, 22(1), 2001, pp. 84-86
Polyaniline film electrode was prepared by constant potential electrolysis.
Effects of sweep rate, monomer concentration and temperature on its electr
ocatalytic performance for polymerization of aniline monomer were studied.
Compared with the blank platinum electrode, the potential of the oxidation
polymerization of aniline monomer on the polyaniline film electrode shifted
negatively. It is showed that the polyaniline film has obvious catalytic a
ction in the polymerization. In addition, the redox peak current on polyani
line film electrode linearly depends on the square root of the potential sw
eep rate. It is indicated that the electrode reaction on polyaniline film i
s controlled by diffusion process.
