Abstract The copolymers of aniline(AN)/m-aminobenzenesulfonic sulfonic acid (MSA) or aniline(AN)/p-aminobenzenesulfonic sulfonic acid (PSA) were prepared by cyclic voltammetry on stainless steel mesh substrates in AN/MSA or AN/PSA mixed monomer solutions, followed by changing the scan rates of polymerization, testing rates and electrolytes to test their electrochemical activity using cyclic voltammetry . The results showed that the electrochemical activities of the copolymers increased with increasing AN/MSA or AN/PSA mole ratios, scan rates of polymerization and testing rates. In addition, the MSA-doped polyaniline was better than PSA-doped in retaining electrochemical activity in neutral solution.
