中文摘要:
      为得到导电性良好的棉织物,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表面方阻、增重率、耐摩擦性能和拉伸断裂强度进行测试。探讨了温度、pH、NiSO4·6H2O 浓度、NaH2PO2·H2O浓度对棉织物增重率、表面方阻的影响。结果表明:在m(NiSO4·6H2O):m(NaH2PO2·H2O):m(H2O)=1.5:2:30,温度60 ℃,频率为40 KHz,功率为320W的条件下超声活化30 min后,以NiSO4·6H2O浓度25 g/L,NaH2PO2·H2O浓度20~25 g/L,Na3C6H5O7·2H2O浓度5 g/L,C2H3NaO2浓度5 g/L,温度90 ℃,pH 5~6,反应时间1 h时。所制备的镀镍导电棉织物表面方阻最小,最好可达71.67 mΩ/□且具有良好的耐摩擦性能。良好的导电性以及耐摩擦性能使其能更好的应用在智能纺织品上。
英文摘要:
      In order to obtain a cotton fabric with good conductivity, an electroless nickel-plated conductive cotton fabric is prepared by the nickel sulfate ultrasonic activation method. The chemical composition and surface morphology of the coating were characterized by EDS and SEM, and the surface square resistance, weight gain, friction resistance and tensile strength of the cotton fabric after nickel plating were tested and analyzed. The effects of temperature, pH, NiSO4·6H2O concentration and NaH2PO2·H2O concentration on the weight gain and surface square resistance of cotton fabric were discussed. The results show that: after m(NiSO4·6H2O): m(NaH2PO2·H2O): m(H2O)=1.5:2:30, temperature 60 ℃, frequency 40 KHz and power 320W, ultrasonic activation for 30 min under the conditions of NiSO4·6H2O concentration 25 g/L, NaH2PO2·H2O concentration 20~25 g/L, Na3C6H5O7·2H2O concentration 5 g/L, C2H3NaO2 concentration 5 g/L, temperature 90 ℃, pH 5~6, reaction time 1h. At this time, the surface resistance of the nickel-plated conductive cotton fabric is the smallest, preferably 71.67 mΩ/□, and has good abrasion resistance. Good electrical conductivity and abrasion resistance make it better applied to smart textiles.
