Problems solved by technology

To obtain a pure copper coating, hydrazine can be used as a reducing agent. However, the catalytic activity of copper to the hydrazine reduction reaction is not high. To obtain a certain thickness of the coating, it is necessary to use the self-catalytic activity of nickel, and deposit nickel to assist continuous deposition of metallic copper.

Abstract

The invention relates to a method for activating electroless copper-plated textile with a nickel salt. The method comprises the steps of soaking the textile into a 10-30g / L coarsening liquid, heating to 60 DEG C and preserving heat for 30min, next, heating to 90 DEG C and preserving heat for 60min, and then washing and drying; soaking the textile into a chitosan solution, soaking twice and rolling twice, and air-drying; soaking the textile in a nickel sulfate solution at the normal temperature, and then soaking into a sodium borohydride solution, cleaning and air-drying to obtain the activated textile, and finally, soaking in an electroless copper plating liquid for plating, and finally washing with water and drying. A macromolecule adsorption nickel salt activating fluid developed in the method is friendly to the environment and capable of either improving the binding force of a coating and the substrate textile or activating a palladium salt with a nickel salt, and therefore, the activation cost is low and the pollution caused by noble metals is reduced, and the method is high in operability.

Description

technical field [0001] The invention belongs to the field of preparation of functional textiles, in particular to a method for activating electroless copper-plated textiles with nickel salts. Background technique [0002] When the noble metal activated electroless plating process is applied on a large scale, it causes problems such as high production cost and unstable activation solution. The nickel salt reduction method is to reduce the metal ions in the nickel salt solution by selecting a suitable reducing agent to obtain metal particles to form catalytic active centers. Zhang Jingdi and others used methanol as a solvent to enhance the adsorption of nickel acetate on polyester fabrics by using the solubilization of surfactants, and used potassium borohydride to directly adsorb nickel acetate on polyester to form an activation center. In order to combine the active metal with the substrate by chemical adsorption to improve the bonding force of the coating, the surface of t...
