Problems solved by technology

Through strong acid treatment, the carbon nanotubes will be damaged to a certain extent, and the use of surfactants will make the surfactants difficult to remove in the final carbon nanotubes and conductive polymer composites
Therefore, the performance of carbon nanotubes and conductive polymer composites obtained after treatment with strong oxidizing acids or surfactants will be affected, and the use of strong oxidizing acids is not environmentally friendly
In addition, because carbon nanotubes are easy to agglomerate, they have not been well dispersed at present. The carbon nanotubes prepared in the prior art and the carbon nanotubes in the conductive polymer composite usually do not form a good conductive network, and some phase The distance between adjacent carbon nanotubes is large, and the contact between them is poor, so the excellent electrical conductivity and thermal conductivity of carbon nanotubes cannot be fully utilized, resulting in a large internal resistance of the carbon nanotubes and the conductive polymer composite material. lower specific capacitance

Abstract

The invention discloses a preparation method of a conducting polymer composite nano-film material and relates to the technical field of conducting polymer composite materials. The preparation method comprises the following steps: a graphene oxide and carbon nano-tube composited nano-film is formed on a substrate firstly, then the nano-film is polymerized in a gaseous environment containing conducting polymer monomers, graphene oxide is reduced, and the conducting polymer film attached to the surface of a nanostructure is formed. The conducting polymer composite nano-film material prepared with the method has the advantages of excellent conducting performance, high specific surface area and environment-friendly process, the phenomenon that graphene oxide after reduction in a liquid phase reaction is not dissolved in water but forms a flocculent precipitate and hinders follow-up film forming in the prior art is avoided, and the problems of non-uniform film forming and difficulty in thickness control due to the phenomenon are solved; the preparation process is simple, the flow is controllable, and the application range of the conducting polymer composite nano-film material is expanded greatly.
