Designing a ternary composite of PPy-PT/ TiO2using TiO2, and multipart-conducting polymers for supercapacitor application

Conducting polymers, polythiophene (PT) and polypyrrole (PPy) were prepared by chemical oxidative polymerization (COP) method. A ternary PPy-PT/TiO(2)composite involve the blending of two polymers namely polythiophene and polypyrrole and further, addition of TiO(2)nanoparticles in the multipart-polymer. PPy-PT/TiO(2)composite exhibits the highest specific capacitance of 271.8 F/g as compared to PT/TiO2(109.6 F/g) and PPy/TiO2(80.4 F/g), respectively. Multipart-conducting polymers boost the conductivity of fabricated device(,)which enhanced specific capacitance of TiO(2)based supercapacitor network, due to their improved surface area, that offers large energy storage and additional pseudocapacitance.
