Abstract
A novel N-substituted aniline, N-(4-sulfonicbutyryl)aniline was synthesized and subsequently to be electropolymerized to yield a new conductive polymer, poly( N-(4-sulfonicbutyryl)aniline). X-ray photoelectron spectrum (XPS) of the polymer film was examined to propose the polymer molecular structure. The sulfonated polyaniline was also characterized by 1H NMR, TGA, DTA, FTIR, and UV–vis spectra. The sulfonated polyaniline showed high conductivity in neutral aqueous solutions, which is two orders of magnitude higher than that of poly( N-acetylaniline) (PNAANI).
