摘　　要：采用氯乙酸钠对棉织物进行阴离子改性,以提高棉织物对氨基化碳纳米管(CNTs-NH2)的吸附性能。探究了氯乙酸钠和CNTs-NH2质量浓度、处理温度、处理时间和浸渍液pH对改性棉织物导电性能的影响,得到CNTs-NH_(2)对棉织物的较佳改性和导电整理工艺:氯乙酸钠150 g/L,CNTs-NH22 g/L,pH=6,在80℃浸渍处理60 min,改性棉织物的表面电阻值可降低至0.67 kΩ/cm,并且导电棉织物具有较好的导电耐洗性。Anionic modification of cotton fabric with sodium chloroacetate is carried out to improve the adsorption performance of cotton fabric on aminoated carbon nanotubes(CNTs-NH2). The effects of the mass concentration of sodium chloroacetate and CNTs-NH2, the treatment temperature, the treatment time and the pH of the impregnation solution on the conductivity of the modified cotton fabric are investigated. The modification and conductive finishing process of CNTs-NH2on the cotton fabric are optimized as: 150 g/L of sodium chloroacetate, 22 g/L of CNTs-NH_(2), pH=6, impregnation at 80 ℃ for 60 min. The surface resistance of the modified cotton fabric can be reduced to 0.67 kΩ/cm, and the cotton fabric has good conductivity and washability.
