Problems solved by technology

Although these methods can obtain high-quality reduced graphene, the equipment used is expensive, the chemical reagents pollute the environment, the controllability is poor, and the operation is complicated.
In addition, the high-temperature reduction method will not only damage the fiber structure, but also the product is rich in impurities, making it difficult to obtain graphene with high purity.

Abstract

The invention relates to a method for preparing a conductive fabric by electrochemical reduction of graphene oxide, and belongs to the field of functional textiles. The method comprises the following steps: pretreating a fabric by a cation polymer, adsorbing the graphene oxide after the fabric is cationized, and reducing the graphene oxide by an electrochemical driving mode to promote a film forming process of the graphene oxide. According to the method, the problem that the conductivity of the fabric is affected because an obtained deposit film is thinner, low in adhesion and easy to crack as the physical acting force between the graphene and the fabric is low and the precursor is low in self-reacting driving force in the current film forming technologies such as rolling, spray-coating and spin-coating is solved; furthermore, by adoption of the technology, the surface of the deposit film is dense, and the thickness is adjustable; a coarse surface can be constructed favorably; meanwhile, the handfeel of the fabric cannot be affected, and the fabric can be widely applied to a functional textile.

Description

technical field [0001] The invention relates to a method for preparing conductive fabrics through electrochemical reduction of graphene oxide, which belongs to the field of functional textiles. Background technique [0002] Conductive fabric is a new type of fabric material, which combines the flexibility, weavability, and low density of ordinary fabrics, as well as the electrical properties and multi-functionality of materials. It can be widely used in antibacterial fabrics, wearable biosensors, energy storage, electronic components and other fields. Generally, conductive fabrics are prepared by preparing conjugated polymers, carbon nanotubes, metal powders, and the like. However, these preparation methods are complicated, and the outdoor stability, flexibility and uniformity of the coating are poor. [0003] Graphene is a new type of carbon two-dimensional nanomaterial, which has excellent high strength, electrical conductivity, thermal conductivity, light transmission, ...
