Abstract

Redox reactions and structural changes of a poly(2,2′-dithiodianiline) [poly(DTDA)], a conducting polymer interconnected with disulfide (S-S) bonds, in acid aqueous solution of various pH values are discussed. We proposed the poly(DTDA) as a proton-exchange type of energy storage material. The cyclic voltammograms (CVs) for poly(DTDA) showed a reproducible redox couples for repeated (10,3-104cycles. To investigate the structure of the poly(DTDA) for each potential and the pH value, a plot of E° vs. pH values obtained from the results of CVs (Pourbaix diagram) was formed and discussed.
