Titanium dioxide@polypyrrole core–shell nanowires for all solid-state flexible supercapacitors†
Abstract
Herein, we developed a facile two-step process to synthesize TiO2@PPy core–shell nanowires (NWs) on carbon cloth and reported their improved electrochemical performance for flexible supercapacitors (SCs). The fabricated solid-state SC device based on TiO2@PPy core–shell NWs not only has excellent flexibility, but also exhibits remarkable electrochemical performance.
