摘要：Molybdenum trioxide/carboxyl functionalized carbon multi-wall nanotubes/poly(5-carboxylindole) (MoO3/ MWCNT-COOH/P5ICA) ternary composites were prepared as supercapacitor electrodes by hydrothermal and electrochemical polymerization methods. When three materials are composite used as electrodes for supercapacitors, the advantages of each material can be effectively integrated, resulting in low impedance and high capacitance characteristics. After optimizing the electrochemical polymerization time of P5ICA, the maximum specific capacitance of the composite electrode can reach 165.6 mF cm-2. The symmetric supercapacitor constructed with composite electrodes demonstrates a maximum specific capacitance of 61.0 mF cm-2, and the area specific capacitance can remain 74 % of the original after 1000 charge and discharge cycles. This study provides a feasible scheme for preparing high performance supercapacitor materials.
