Summary: Conducting polymers are promising transparent supercapacitor electrode materials due to their high conductivity, environmental stability, light weight, and ease of synthesis. We developed a synthetic method to covalently link poly(3,4-ethylyenedioxythiophene) (PEDOT) and glass, which overcomes the poor adhesion and low cycling stability challenges. This method enables the fabrication of current collector-free planar supercapacitor electrodes on any glass surface.
