摘要
The chemical synthesis of polyaniline (PAni) in a reactional medium containing sulphanilic acid (AS) as a dopant agent leads to a polymer with an electrical conductivity of 3 S cm(-1). Thermogravimetrical analysis (TGA) showed that the doped polymer PAni-AS had a degradation temperature lower than the emeraldine-base polymer, due to the loss of the doping agent, water and low molecular weight oligomers. Scanning electronic microscopy (SEM) allowed to see that the polymer morphology is similar to other polymers described in the literature. (C) 1999 Elsevier Science S.A. All rights reserved.
