摘要：In this paper, poly(indole-5-carboxylic acid)/molybdenum disulfide (P5ICA/MoS2) multilayer composites supported by MoS2 nanosheet arrays were prepared by hydrothermal method and electrochemical deposition method. Due to the good synergy of the electrochemical properties of P5ICA and MoS2, the nanocomposites show good electrochemical performance. The maximum specific capacitance of the composite electrode can reach 476.04 F g- 1, and 87.6 % of the original specific capacitance can be maintained after 1000 charge and discharge cycles. The characterization results show that the unique morphology of the composite electrode makes it have low impedance and high capacitance. In addition, the maximum specific capacitance of the symmetrical supercapacitor assembled with composite electrodes is 317.44 F g- 1, and 52.17 % of the original specific capacitance can be maintained after 1000 charge and discharge cycles. This result shows that the polymerization of P5ICA on MoS2 nanosheets can effectively combine the high pseudocapacitance performance of P5ICA with the high stability of MoS2 nanosheets to form a synergistic effect and improve the overall performance of the material. This study has important theoretical value and practical significance for the preparation of high performance organic-inorganic composite electrodes.
