Abstract

The invention relates to a method for preparing a graphene loaded ordered polyaniline nanorod array electrode material by low temperature interface polymerization, comprising the following steps: using sulfonated graphene as a carrier, dispersing the sulfonated graphene uniformly in an acidic aqueous solution containing dissolved oxidizing agent, dissolving aniline in an organic solvent, then transferring one phase into the other phase, standing for reaction at a low temperature. The prepared graphene loaded polyaniline composite material has an array of polyaniline nanorods vertically orderly arranged on the surface of the graphene base layer. The composite material has high specific capacitance, multiplying power characteristic and electrochemistry circularity and other excellent characteristics, and can be applied in high energy storage density super capacitor materials.

Description

technical field

[0001] The invention belongs to the field of new energy materials, and relates to a preparation method of a supercapacitor electrode material, in particular to a preparation method of a graphene-loaded ordered polyaniline nanorod array electrode material. Background technique

[0002] Polyaniline is one of the most representative conductive polymers. It has the characteristics of cheap raw materials, easy preparation, excellent environmental stability, high theoretical specific capacitance, and non-toxicity. It is widely used as an electrode material for supercapacitors. However, during the charge-discharge cycle, the volume of polyaniline repeatedly expands / shrinks, causing damage to the polymer chains, resulting in unsatisfactory electrochemical stability. At the same time, the conductivity of polyaniline is greatly affected by the pH of the system and the working potential. This restricts its application in electrode materials.
