Electrochemical activity and structure of new composite systems based on cross-linked polyacrylamide and polyaniline

A procedure was developed for preparing electroactive composite systems based on polyacrylamide hydrogel and a conducting polymer, polyaniline. The overall electrical conductivity of the composite systems was measured by chronoamperometry, and the contributions of the electronic and ionic constituents were calculated. The specific capacity of the composites was calculated using galvanostatic charge-discharge cycles, and the stability of the capacity at cycling was evaluated.
