Abstract

The invention relates to a method for making conductive fabric through polyaniline-triggered chemical slivering. Fabric is soaked in a mixed solution of aniline and protonic acid, ammonium persulfate is added to the mixed solution, a reaction is carried out for 2-10 hours, and then the processed fabric is obtained after washing; the processed fabric is soaked in a silver nitrate solution, washed, dried, and then soaked in a silvering solution for being silvered for 30-60 min at the temperature of 30-40 DEG C, then the processed fabric is washed and dried, and finally the conductive fabric is obtained. According to the method, the process conditions of sensitization and activation are omitted, polyaniline and silver nitrate replace stannous chloride and palladium chloride high in price, cost is lowered, and environment pollution is reduced. The conductive fabric obtained through the method is good in conductivity, the binding strength of metal and fabric is high, the electromagnetic shielding performance is excellent, and the conductive fabric has an antistatic function, an antibacterial function and the like.

Description

technical field [0001] The invention belongs to the field of preparation of conductive fabrics, in particular to a method for preparing conductive fabrics using polyaniline to trigger chemical silver plating. Background technique [0002] With the development of science and technology, electronic technology products have penetrated into all aspects of people's life and production. In order to improve the efficiency of use, the transmission power is often larger and larger, and the problem of electromagnetic radiation also follows. Anti-electromagnetic radiation fabrics are mainly Electromagnetic waves are shielded by reflection loss and absorption loss. The reflection method is mainly realized by the metal layer on the surface of the fabric, and the absorption method is mainly realized by high molecular conductive polymer. The processing method combining conductive polymers and metal conductive layers will be more advantageous. The conductive textiles prepared by this method...
