The effect of solution temperature on the mass transport properties of PPy conducting polymers doped with different 2 2 2 dopants such as p-toluene sulfonate (PTS ), dodecyl sulfate (DS ) and dodecyl benzene sulfonate (DBS ) counterions was investigated. The electrochemical quartz crystal microbalance (EQCM) technique was employed to investigate the ion-exchange properties of the polymers at different solution temperatures. It was found that the size of the counterion employed during synthesis had a determining effect on the ion-exchange properties of PPy conductive electroactive polymers. The ion-exchange properties of PPy are also affected by the solution temperature.
