Abstract

The invention discloses a graphene layer-by-layer assembling-based flexible conductive waterproof fabric. The flexible conductive waterproof fabric mainly comprises, by weight, 0.1-1 part of graphene oxide, 1 part of a cellulose fabric and 0.5-5 parts of a reducing agent. A production method of the flexible conductive waterproof fabric comprises the following steps: impregnating 1 g of the fabric in a 0.1-1% aqueous solution containing the graphene oxide, carrying out ultrasonic treatment under a pH value of 6-8 at a temperature of 20-60 DEG C for 10-40 min, drying the treated fabric at 80-100 DEG C, and repeating the impregnation, ultrasonic treatment and drying steps multiple times; and impregnating the obtained graphene layer-by-layer assembled fabric in a reducing agent solution with the concentration of 0.5-5%, reducing the fabric at 80-90 DEG C for 0.5-3 h, washing the reduced fabric with water multiple times, and drying the washed fabric at 80-100 DEG C to obtain the flexible conductive waterproof fabric. Graphene selected as a conductive finishing agent improves the conductive effect, and also keeps the good strength and the good waterproof performance of the fabric.

Description

technical field [0001] The invention relates to the field of smart textiles, in particular to a graphene-based assembled fiber fabric, which is a smart textile with flexibility, electrical conductivity and water resistance. Background technique [0002] Fibrous electronic devices with excellent electrical conductivity and excellent flexibility can be woven into various fabrics and combined with people's daily wear to prepare smart fabrics. There are three main types of conductive textiles: the first is metal-based conductive textiles. Metal fiber has good electrical conductivity, heat resistance and chemical corrosion resistance. But for textiles, metal fibers have small cohesion, poor spinning performance, poor coloring of finished products, and poor hand feeling, so they are only suitable for weaving into T / C fabrics, and are used for work in flammable and explosive industries such as oil fields and chemical plants. . The second is carbon black-based conductive textiles...
