摘　　要：采用硫酸镍超声活化法制备化学镀镍导电棉织物。用EDS和SEM对镀层的化学成分以及表面形貌进行表征,并对镀镍后棉织物的方阻、增重率、耐摩擦性能和拉伸断裂强力进行测试。探讨了温度、pH、NiSO_(4)·6H_(2)O及NaH2PO2·H_(2)O质量浓度对棉织物增重率、方阻的影响。结果表明,在m(NiSO_(4)·6H_(2)O)∶m(NaH_(2)PO_(2)·H_(2)O)∶m(H_(2)O)=1.5∶2.0∶30.0,温度60℃,频率为40 kHz,功率为320 W的条件下超声活化30 min后,以NiSO_(4)·6H_(2)O质量浓度25 g/L,NaH2PO2·H_(2)O质量浓度25 g/L,无水柠檬酸钠质量浓度5 g/L,CH3COONa质量浓度5 g/L,温度90℃,pH为5,反应时间1h镀镍后,所制备的镀镍导电棉织物方阻最小,可达71.67mΩ/□,且摩擦18800次时,减重率为3.94%。无钯活化镀镍棉织物拥有良好的导电性及耐摩擦性能,能更好地应用在智能纺织品上。An electroless nickel-plated conductive cotton fabric was prepared by nickel sulfate ultrasonic activation method.The chemical composition and surface morphology of the coating were characterized by EDS and SEM.The square resistance,weight gain,abrasion resistance and tensile breaking strength of the cotton fabric after nickel plating were tested and analyzed.The effects of temperature,p H,mass concentration of NiSO_(4)·6H_(2)O and NaH2PO2·H_(2)O on the weight gain and square resistance of cotton fabric were discussed.The results showed that the ultrasonic activation conditions were obtained as follows:m(NiSO_(4)·6H_(2)O)∶m(NaH_(2)PO_(2)·H_(2)O)∶m(H_(2)O)=1.5∶2.0∶30.0,60℃,40 kHz,320 W and 30 min.When NiSO_(4)·6H_(2)O,NaH2PO2·H_(2)O,C6H5Na3O7 and CH3COONa mass concentrations were 25,25,5 and 5 g/L,temperature was 90℃,pH=5,and reaction time of 1 h,the square resistance of the nickel-plated conductive cotton fabric was the smallest(71.67 mΩ/□),and the weight loss rate was 3.94%after being rubbed 18800 times.Palladium-free activated nickel-plated cotton fabric had good electrical conductivity and abrasion resistance,which can be better applied to smart textiles.
