Abstract

The invention discloses a preparation method of a conductive polymer carbon material composite thin film; the preparation method comprises the following steps of step 1), preparation of a colloidal water solution of hydroxylated multi-walled carbon nano tubes; step 2), assembling of a carbon nano tube oil / water interface; and step 3), electrochemical synthesis of the conductive polymer carbon material composite thin film. By virtue of the PPY / FCNTs composite film, performance complementation of PPY and FCNTs can be realized, and the overall conductivity, the charge migration rate and the stability of the of the composite film are improved; and meanwhile, the composite film has a special three-dimensional net structure, so that the migration of electrons and ions in the charging and discharging process is facilitated, and the energy storage performance is obviously enhanced.

Description

technical field [0001] The invention relates to the field of conductive film preparation. More specifically, the present invention relates to a preparation method of a conductive polymer carbon material composite film. Background technique [0002] Conductive polymers, such as polyaniline (PANI), polypyrrole (PPY), poly-3,4-ethylenedioxythiophene (PEDOT), etc., have good conductivity, high charge storage capacity, and environmental friendliness in the doped state Stability and excellent reversibility [1-3] And other characteristics, are widely used in energy storage and other fields, such as supercapacitors, solar cells and so on. However, conductive polymer electrode materials tend to swell and shrink during charging and discharging, which makes the mechanical properties of conductive polymer-based electrodes deteriorate and the capacitance performance decays during cycling. At present, nanomaterials with large specific surface area, high conductivity and good cycle stab...
