The polymerization of aniline on the p-Si electrode was investigated b
y in situ Fourier transform infrared-attenuated total reflection spect
roscopy. Results show that the N-H vibrational mode of aniline: in the
3490-3050 cm(-1) range, shifts to lower wave number when the applied
electrode potential becomes more positive. There is no benzidine inter
mediate in this polymerization process. The IR adsorption spectrum of
the polyaniline spectrum obtained by the in situ method is similar to
that obtained by ex situ IR transmission detection. The mechanism of p
olyaniline synthesis on the p-Si electrode is discussed. (C) 1996 Amer
