|
摘要
为开发导电棉织物并改善其导电性能,采用层层自组装技术,将羧基化碳纳米管和氨基化碳纳米管用于棉织物的导电整理。以电导率为指标,通过单因素分析对羧基化碳纳米管和氨基化碳纳米管的质量浓度、组装时间以及组装层数进行优化,并研究在优化工艺条件下制备的复合导电棉织物的表面形貌、化学结构和耐水洗牢度。结果表明:羧基化碳纳米管、氨基化碳纳米管质量浓度均为1. 5 mg/m L,组装时间为15 min,组装层数为8时,复合导电棉织物的电导率为3. 42 S/m,具有较好的导电性;经10次洗涤后棉织物电导率降为2. 88 S/m,具有很好的耐洗效果。
In order to develop conductive cotton fabrics and improve the conductivity of the cotton fabrics,carboxylated carbon nanotubes and aminated carbon nanotubes were used in conductive finishing of cotton fabrics by layer-by-layer self-assembly. Using the conductivity as an index,the concentration of carboxylated carbon nanotubes and aminated carbon nanotubes,the assembly time and the assembly layer number were optimized by single factor analysis. Under the optimized process conditions,the surface morphology,chemical structure and washing fastness of the composite conductive cotton fabrics were investigated. The results show that when the concentration of carboxylated carbon nanotubes and aminated carbon nanotubes is 1. 5 mg/m L respectively,the assembly time is 15 min and the assembly number is 8,the conductivity of the composite conductive cotton fabric is 3. 42 S/m,proving that the composite conductive cotton fabric has good conductivity. The conductivity can reach 2. 88 S/m after washing for10 times,showing that the composite conductive cotton fabric has good washing fastness.
