The preparation method of the palladium-free activated nickel-plated conductive cotton fabric comprises the following steps of performing oil removal, coarsening, ultrasonic activation and chemical nickel plating on cotton fabric to obtain the conductive cotton fabric, wherein an activating solution adopted in the ultrasonic activation step comprises the following components: a reducing agent, nickel sulfate hexahydrate andwater, and the mass ratio of reducing agent to nickel sulfate hexahydrate to water is 2:1.5:30. The preparation method of the palladium-free activated nickel-plated conductive cotton fabric is simpleto operate, short in process flow and low in production cost, and the palladium-free activated nickel-plated conductive cotton fabric is endowed with good conductivity on the premise of ensuring uniform nickel plating of the cotton fabric.

Description

technical field [0001] The invention relates to a palladium-free activated nickel-plated conductive cotton fabric and a preparation method thereof, belonging to the field of functional materials. Background technique [0002] There are many ways to conduct electricity in cotton fabrics, including metal wire blending, coating conductive materials on the surface, vacuum coating, magnetron sputtering, chemical vapor deposition, etc., but the conductive cotton fabrics made by these methods have poor wear resistance and are easy to wear. The damage cannot be used for a long time or in a special environment to achieve the desired wear-resistant and conductive effects. [0003] The commonly used method for preparing conductive fabrics is electroless plating. Although the electroplating method can give the fabric a certain wear resistance, but because the types of electroless plating on cotton fabrics include nickel, copper, silver and other metals, copper is not weather-resistant a...

AI Technical Summary

Problems solved by technology

The traditional activation process adopts metal palladium and colloidal palladium activation method, the palladium ions are reduced to metal palladium and attached to the fabric through reaction, and then the nickel ions in the solution are replaced by metal palladium to form metal nickel through the replacement reaction, so as to realize the chemical plating of fabrics. Nickel, but cannot be mass-produced due to the high cost of metal palladium

In recent years, nickel salts have been used to replace palladium salts for activation, and nickel acetate to establish nickel active sites at around 205°C has become the mainstream for nickel plating. However, the temperature is too high and the energy consumption is large, so it cannot be well applied to the activation of cotton fabrics.
