Abstract

Electrochemical polymerization effectively deposits polypyrrole (PPy) onto activated carbon polyester felt fabric (ACPFF) to create a novel flexible supercapacitor electrode. TiO₂ nanoparticles were used in the electrochemical polymerization process to improve the supercapacitor performance of the electrode. Electrochemical experiments revealed that adding TiO₂ improved the electrochemical performance of ACPFF-PPy. The cyclic voltammetry studies revealed a considerable increase in specific capacitance at various scan rates and increased from 53.5F/g to 121F/g for ACPFF-PPy and ACPFF-PPy-TiO₂, respectively, at a scan rate of 5 mV/s. The capacitance obtained from galvanostatic charge–discharge measurements increased by 353 % at a current density of 1.5 A/g due to TiO₂ addition. The examined electrodes demonstrated good long-term cycling stability, with retentions of 81 % for ACPFF-PPy and 85 % for ACPFF-PPy-TiO₂ after 2400 cycles.

期刊介绍： The journal provides an international medium for the publication of theoretical and experimental studies and reviews related to the electronic, electrochemical, ionic, magnetic, optical, and biosensing properties of solid state materials in bulk, thin film and particulate forms. Papers dealing with synthesis, processing, characterization, structure, physical properties and computational aspects of nano-crystalline, crystalline, amorphous and glassy forms of ceramics, semiconductors, layered insertion compounds, low-dimensional compounds and systems, fast-ion conductors, polymers and dielectrics are viewed as suitable for publication. Articles focused on nano-structured aspects of these advanced solid-state materials will also be considered suitable.
