Cyclic voltammetry and conductivity investigations of polyaniline

摘要

AbstractThe cyclic voltammograms of polyaniline prepared electrochemically were examined in the range −0.2 to 1.0 V vs. SCE in the presence and absence of aniline in the acqueous solution of HBF4. Cyclic voltammetry studies show that the polymeric film suffers degradation when the potential exceeds +0.85 V, and below this potential, it is quite stable. The redox reaction of the film is reversible. The polymeric film synthesized at low temperature and high acid concentration exhibits higher electronic conductivities. © 1993 John WileySons, I
