The electrochemical growth of thick (similar to 2 mm) emeraldine, polyanili
ne (PANI(E)) films from solutions containing 2 M HBF4 and 0.25 M aniline is
demonstrated. Electrochemically and chemically prepared PANI(E) films, cas
t from formic acid solutions, are compared. The combination of electrochemi
cal results with Fourier transform infrared spectroscopic data indicates th
at pure and homogeneous standard material can be reproducibly prepared elec
trochemically. (C) 1999 The Electrochemical Society. S0013-4651(99)07-040-8
