Abstract
Work has focused on developing a polymerization approach to control porosity and to investigate the redox behaviour of conducting polymer/heteropolyoxometalate composites. Results to date have demonstrated an ability to control porosity by varying the weight percent of sodium sulfate crystals (insoluble in THF) in the polymerization mixture, thereby controlling the density of crystals in the polymer films produced by spin coating the mixture onto a substrate. The porous films were then generated by dissolution of the crystals in water leaving behind the polymer. Increasing the porosity of the films in this manner increases rate at which the redox state of the polymer can be switched. This behaviour is attributed to an increase in the ionic conductivity and a lowering of the RC time constant of the material.
