Abstract

We report exceptional electrochemical specific capacitance (640 F g⁻¹) for polythiophene (PTh) infiltrated into TiO₂ 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.
