MACROMOLECULAR COMPOUNDS AND POLYMERIC MATERIALS 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 specifi c capacity of the composites was calculated using galvanostatic charge-discharge cycles, and the stability of the capacity at cycling was evaluated.
