摘要：

The annealing effect on the electroactivity of polyaniline (PAn) complexed with various acids has been investigated. The polyaniline-p-toluene sulfonic acid complex (PAn-pTSA) and polyaniline-hydrochloric acid complex (PAn-HCl) show decreased electroactivities with annealing temperature, but the polyaniline-dodecylbenzene sulfonic acid complex (PAn-DBSA) shows an increase in electroactivity up to an annealing process of 150 degrees C, and then a decrease at an annealing process of 180 degrees C. The increase of the electroactivity for PAn-DBSA can be explained by an additional thermal doping of undoped DBSA with annealing. The electrical conductivities at a high temperature of 230 degrees C are in the order of PAn-pTSA > PAn-DBSA > PAn-HCl. PAn-pTSA shows the highest conductivity because pTSA shows the most thermal stability. Decreased conductivity at a high temperature may be due to the dedoping and structural change that cannot be recovered by redoping. (C) 1998 Elsevier Science S.A. All rights reserved.
