Polythiophene infiltrated TiO2 nanotubes as high-performance supercapacitor electrodes

Abstract

We report exceptional electrochemical specific capacitance (640 F g(-1)) for polythiophene (PTh) infiltrated into TiO(2) nanotubes (TNTs) by a controlled electropolymerization route. The resulting PTh-TNTs also exhibit excellent electrochemical behavior with long-term stability. This reproducible and superior performance of PTh-TNT electrodes makes them attractive candidates for energy storage.
