Abstract

The invention relates to a preparing method for a copper ammonia fiber conductive textile. According to the preparing method, copper ammonia fibers serve as a base material, and polypyrrole layers and copper layers are deposited on the surfaces of the copper ammonia fibers in sequence. The specific technology comprises the steps of cleaning the copper ammonia fibers, carrying out polypyrrole in-situ chemical polymerization, carrying out self-assembly modification through a silane coupling agent, adsorbing cupric ions, reducing potassium borohydride, carrying out electroless copper plating and the like. According to the preparing method, the copper ammonia fibers serve as the base material of the conductive textile, and thus degradation of the materials and recovery and recycle of copper are facilitated. The copper ammonia fibers and conductive substances (polypyrrole and copper) are combined, the ammonia fibers are changed into a conductor from an insulator, and thus the application of the ammonia fibers is developed. The silane coupling agent can serve as a molecule bridge of the polypyrrole layers and the metal layers, and the reliability of products is improved. Conductive macromolecule chemical polymerization and chemical plating are combined, and thus the problems that a conductive textile prepared from macromolecule polymerization or chemical plating alone is poor in conductivity, low in shielding effect and the like are solved. The cost is low, the process is simple, and the degree of dependency on instruments and equipment is low.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to a preparation method of cupro ammonia fiber conductive textiles. Background technique [0002] Conductive textiles are widely used in various textiles because of their good electrical conductivity, electromagnetic shielding, light weight, easy processing, and breathability, such as: clothing textiles, decorative textiles, industrial textiles and new types of textiles. Medical Textiles. The process of preparing conductive textiles can be roughly divided into two categories, one is the introduction of conductive components (metal powder or carbon powder) in the chemical spinning stage, the mixing and twisting of fibers with metal wires or carbon fibers in the mechanical spinning stage, and the use of intrinsic Conductive polymers (polypyrrole, polyaniline, polythiophene, polyacetylene, etc.) are solution or melt spun. This type of method is highly depende...
