Intrinsically conducting polymers are of great interest for use as electrochemical capacitors, electrochromics, cancer therapies, and chemical and biological sensors. Surface area has a profound impact on performance of these polymers. While the electrochemical deposition of conducting polymers may introduce porosity and increase surface area, solution-cast films of conducting polymers typically exhibit low porosity. We have explored hard and soft templating approaches as well as deposition of conducting polymer emulsions as ways of controlling polymer surface area. The impact of these treatments on polymer morphology, optical properties, and electrochemical properties will be discussed.
