NANO-NETWORK CONDUCTING POLYMERS AS SUPERIOR ELECTRODES FOR SUPERCAPACITORS

Abstract

The characteristics of supercapacitor with a series of 3,4-alkylenedioxythiophene (XDOT) derivatives through the controlling of the ring size and substitutions variation have been investigated. The results indicated that more-open morphology of the polymers produced the excitant of the bulky group on the monomer, which produce the ionic transfer during the redox reaction leading to higher specific capacitance and better stability. Poly(3,4-propylenedioxythiophene) PProDOT shows a highest specific capacitance (125 F g^-1) which can maintain more than 85% of its original values after 1k cycles compared with other polymers.
