以涤纶织物为基材，对其化学镀铜后再化学镀镍–磷合金镀层。探讨了化学镀 Ni–P 合金工艺各因素对镀金属织物导电性和增重率的影响，通过正交试验优化了化学镀Ni–P合金工艺，并对镀Cu/Ni–P合金织物的结合牢度、耐蚀性和电磁屏蔽效能进行了表征。结果表明，涤纶基铜层表面化学镀Ni–P合金镀层的最优配方和工艺为：NiSO4·6H2O 26 g/L，NaH2PO2·H2O 24 g/L，Na3C6H5O730 g/L，Na2B4O7·10H2O 6 g/L，温度80°C，pH 11，时间25 min。最优工艺下制备的镀铜/镍–磷织物的结合强度高，耐腐蚀性和电磁屏蔽性能良好。
Electroless copper plating followed by electroless nickel–phosphorous plating was conducted on polyester fabrics. The influences of different factors of electroless Ni–P alloy plating on the conductivity and weight gain rate of metal-plated fabric were discussed. The process parameters of electroless Ni–P plating were optimized by orthogonal test. The adhesion strength, corrosion resistance, and electromagnetic shielding property of Cu/Ni–P alloy-plated fabric were characterized. The optimal bath composition and operation conditions of electroless Ni–P alloy plating on copper-plated polyester substrate were obtained as follows: NiSO4·6H2O 26 g/L, NaH2PO2·H2O 24 g/L, Na3C6H5O7 30 g/L, Na2B4O7·10H2O 6 g/L, temperature 80 °C, pH 11, and time 25 min. The Cu/Ni–P-plated fabric features strong adhesion strength and good corrosion resistance and electromagnetic shielding property.
