Preparation method of composite conductive fabric

Abstract

The invention discloses a preparation method of a composite conductive fabric, and relates to the technical field of textile materials. The preparation method comprises the following steps of reactingdendritic porous silicon dioxide with poly(allylamine hydrochloride) and potassium chloropalladite; carrying out reduction, carbonization and alkaline etching to obtain a conductive particle blank; mixing the conductive particle blank with dopamine, and filtering the mixture to obtain conductive particles; and finally, mixing the conductive particles with functionalized carbon nanotubes, adding polyacrylonitrile and N,N-dimethylformamide to obtain a spinning solution, spinning the spinning solution into silks, and preparing a fabric from the silks to obtain the composite conductive fabric. The composite conductive fabric prepared by the method has excellent electrical conductivity and relatively high tensile strength.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a method for manufacturing a composite conductive fabric. Background technique [0002] In the current ever-changing Internet of Things technology, the research and development progress of intelligent clothing is extremely important, but the progress of the entire research and development is very slow due to the conductive problem of the fabric. [0003] The conductivity of the fabric depends on the conductivity of the fiber; nowadays, the preparation methods of conductive fibers mainly include the following: 1. Metal processing method, that is, using the conductivity of metal, metal conductive fibers can be obtained through certain processing methods ; 2. Spinning processing method, that is, direct spinning of conductive polymers (such as polyacetylene, polyaniline, polypyrrole, polythiophene, etc.) or conductive polymers, conductive particles (mainly carbon black or m...

Problems solved by technology

[0004] Although there are many methods for preparing conductive fibers nowadays, there are some disadvantages in these preparation methods. For the conductive fibers prepared by the three methods 3, 4, and 5, the conductive layer on the surface of the fiber is easy to fall off during use, so that the fabric cannot be used. Long-term conductivity, 2. Fabrics woven from conductive fibers prepared by methods 1 and 2. Although they have long-term conductivity, the strength of the fabric will be greatly affected.
