Abstract

The invention discloses a preparation method of a graphene / polyaniline self-assembly flexible conductive fabric, which belongs to the technical field of textile chemistry. The method comprises the steps of firstly covering the surface of the fabric with a layer of reduced oxidized graphene (rGO) or a derivative of the reduced oxidized graphene, carrying out in-situ polymerization after the fabric adsorb the polyaniline, covering the graphene arranged fabric with a layer of conductive macromolecular polymer, and repeating the steps to obtain the conductive fabric with excellent effect. By adopting the method, the weakness that the single graphene or graphene derivative arrangement fabric can obtain a good conductive effect only by adsorbing sufficient graphene and the single polyaniline arrangement fabric is poor in stability can be overcome, the prepared conductive fabric is high in conductivity and high in heat resisting stability, and the fabric can be applied to the fields such as medical healthcare, intelligent sensors, mobile power generation and military. The method is applicable to conventional fabrics such as natural fibers of cotton, wool, natural silk, synthesized fibers such as terylene, chinlon and acrylic fibers as well as the blended weaving of the fabric or the conductive arrangement of the intertexture.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and relates to a method for preparing flexible conductive fabrics by self-assembling monomers of graphene or its derivatives and aniline and its derivatives. Background technique [0002] Conductive materials based on textile fibers are the most common flexible conductive materials. They are light, easy to carry, and have good flexibility. They have broad application prospects in flexible electronic devices, smart materials, and new solar cells. Conductive textiles generally include metal conductive fabrics, metal-plated conductive fabrics, polymer composite conductive fabrics, and graphene conductive fabrics. Metal conductive fabrics and metal-plated conductive fabrics are characterized by rough hand feeling and poor comfort. Therefore, people have turned their research focus to high molecular conductive polymer materials and graphene conductive materials. [0003] Graphene exists in...
