A new and novel nanocomposite cation exchanger polyaniline-zirconia (PANI-ZrO2) has been synthesized using a chemical oxidative polymerization of aniline by the incorporation of zirconia nanoparticles via three different chemical polymerization pathways. The PANI-ZrO2 composite was examined for its cation exchange property and utilized for the fabrication of supercapacitor electrodes in the symmetric two electrode cell configuration. The aqueous polymerized PANI-ZrO2 composite showed high specific capacitance (387 F g-1) and capacitance retention of up to 81% after 2500 charge-discharge cycles. The excellent electrochemical performance of the composite is mainly attributed to its nanofibrous structure and high electronic conductivity.
