导电/抗紫外复合纤维的制备及性质研究

Research on preparation of composite fibre and their electrical conductive and anti-ultraviolet properties

利用改性纳米二氧化钛涤棉纤维为基材吸附苯胺,采用紫外光辅助原位聚合法在基材表面合成聚苯胺,制得导电/抗紫外复合纤维。讨论了过硫酸铵用量、盐酸浓度、苯胺用量对导电/抗紫外复合纤维导电性的影响,并优化了制备工艺。通过表面电阻、抗紫外性能和扫描电镜测试,证明了目标纤维兼具有良好的导电性和抗紫外性能,同时证明了纳米TiO_2存在于目标纤维中。

Composite fiber with electrical conductivity and ultra-violet resistance was prepared firstly by adsorbing aniline on cotton-polyester blended fabric,which had been modified by nano-TiO2,and subsequently by synthetizing polyaniline on its surface using ultra-violet assisted in-situ polymerization.Factors influencing on the electrical conductivity of target fiber,viz.,dosage of ammonium peroxydisulfate,concentration of hydrochloric acid,and amount of aniline,were separately discussed,with the preparation process was then optimized.Finally,electrical conductivity and ultra-violet resistance of fiber were respectively characterized by surface resistance test and anti-ultraviolet measurement,and the nano-TiO2 was observed by SEM as well.
