Problems solved by technology

However, due to the π-π stacking effect of graphene and conductive polymers, the effective specific surface area of ​​the composite material is small, and the face-to-face stacking of graphene sheets in the three-dimensional porous network is still the main factor restricting its supercapacitive properties.

Abstract

The invention relates to a preparation method of carbon nano tube co-reinforced conducting polymer hydrogel. The method comprises the following steps that: (1) epoxidized carbon nano tubes are dissolved into an amino-anthraquinone solution, and electroactive molecule grafted carbon nano tubes can be prepared through utilizing a reflux reaction, and stirring is carried out; (2) the electroactive molecule grafted carbon nano tubes prepared in the step (1) are added into a polystyrene sulfonate solution, and the mixture of the electroactive molecule grafted carbon nano tubes and the polystyrene sulfonate solution is stirred; (3) a conducting polymer monomer is added into the solution obtained in the step (2), and the mixture of the conducting polymer monomer and the solution is stirred; (4) an oxidant solution is added into the solution obtained in the step (3); and the mixture of the oxidant solution and the solution stand and react, and an obtained product is purified and balanced in distilled water, so that the carbon nano tube reinforced conducting polymer hydrogel can be obtained. Compared with a pure conducting polymer hydrogel, the carbon nano tube reinforced conducting polymer hydrogel has high conductivity and specific capacitance.

Description

technical field [0001] The invention belongs to the technical field of supercapacitor electrode materials, in particular to a method for preparing a carbon nanotube-reinforced conductive polymer hydrogel. Background technique [0002] Supercapacitors, also known as electrochemical capacitors, are a new type of energy storage device whose performance is between traditional capacitors and secondary batteries. Its power density is significantly higher than that of lithium-ion batteries, and its energy density is 10-100 times that of traditional capacitors. In addition, supercapacitors also have notable features such as short charging time, long cycle life, and environmental friendliness. Therefore, supercapacitors have broad application prospects in the fields of renewable energy power generation grid connection, electric vehicles, information communication, aerospace and other fields. Electrode materials are the key factors affecting the performance and production cost of sup...
