Embodiment

[0040] The polyester fabrics with a size of 5cm×5cm were ultrasonically cleaned with acetone and ethanol for 30min respectively, and the fabrics were taken out, washed in deionized water, and dried in an oven; the cleaned polyester fabrics and nickel acetylacetonate were placed in a supercritical fluid device, Under the condition of 90℃, 10MPa, treated for 20min, take out the polyester fabric, after ultrasonic treatment in 5g / L sodium borohydride for 5min, put it into the electroless copper plating solution, the plating solution contains copper sulfate 14g / L, ethylenediaminetetramine Disodium acetate 20g / L, glyoxylic acid 12g / L, potassium ferrocyanide 10mg / L, heated in a water bath at 70°C, and reacted for 20min; finally, the cloth sample was taken out, washed repeatedly with deionized water, and dried in an oven at 80°C.

[0041] The surface morphology and conductive energy of polyester fabric after supercritical fluid activation treatment and electroless copper plating are as...

Abstract

The invention belongs to the field of functional textile fabrics, in particular relates to a conductive metalized textile fabric treated by supercutical fluid activation, and provides a supercutical fluid activation method of the conductive metalized textile fabric. The conductive metalized textile fabric comprises raw materials, including acetylacetone nickel, carbon dioxide, copper sulfate, ethylenediamine tetraacetic acid disodium, glyoxylic acid, potassium ferrocyanide and the textile fabric. The supercutical fluid activation method comprises the following steps: firstly, performing activation pretreatment on the textile fabric by using acetylacetone nickel through supercritical carbon dioxide, soaking in sodium borohydride solution, and putting the textile fabric into a chemical copper plating solution for chemical plating. The supercritical carbon dioxide is adopted for pretreatment, andglyoxylic acid is used as a reducing agent, so that the conductive metalized textile fabric has the characteristics of environment friendliness, no pollution, low cost and repeatability, and the obtained copper polyester fabric has functions of good conductivity, electromagnetic shielding, electrostatic resistance and the like.

Description

technical field [0001] The invention belongs to the field of functional textile fabrics, in particular to a supercritical fluid activation method for preparing conductive metallized textile fabrics. Background technique [0002] Electroless plating of silver, nickel and copper on the surface of the fabric can make it have special functions such as electrical conductivity, electromagnetic wave shielding, and antistatic. There are steam method, sputter coating method, electroplating method and electroless plating method for coating metal layer on the surface of fabric. Through redox reactions, electroless plating enables metal particles to be more easily and uniformly plated on the surface of the fabric. Electroless silver plating has excellent electrical and thermal conductivity, but the cost is prohibitive. Electroless nickel plating has excellent weather resistance, but is not as conductive as silver and copper plating. Electroless copper plating has received extensive a...
