| Abstract | This study examined the unique self-doping behavior of carboxylated polyaniline (PCA). The selfdoped PCA was synthesized using an environmentally benign enzymatic polymerization method with cationic surfactants. XPS showed that HCl-doped PCA contained approximately 34% of protonated amines but selfdoped PCA contained 9.6% of the doped form of nitrogen at pH 4. FTIR and elemental analysis showed that although the PCA was doped with the proton of strong acids at low pH via the protonation of amines, the selfdoping mechanism of PCA at pH > 4 was mainly due to hydrogen bonding between the carboxylic acid group and amine group. |
