Synthesis ofpoly(3,4-ethylenedioxythiophene)/MXene composite material and its capacitance properties research
MXene material has the advantages of flexible composition and high capacitance,which has attracted much attention in the field of supercapacitor energy storage.In this work,the poly(3,4-ethylenedioxythio-phene)/MXene(PEDOT/MXene)composite electrode material were synthesized via electrochemical method.Experimental results indicate that the specific capacitance of PEDOT/MXene reaches 250.21 mF/cm2 at a scan rate of 30 mV/s.With the current density increasing from 0.1 mA/cm2 to 5 mA/cm2,the specific capacitance retention of PEDOT/MXene achieves 83.5%,was much better than PEDOT(64.1%).Additionally,the initial specific capacitance of PEDOT/MXene still remains 84%over 1 000 cycles at a scan rate of 100 mV/s by CV method,exhibiting good rate performance and cycle stability.This work provides a new approach to construct high-performance energy storage interface with MXene-based materials.
