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。
Polyaniline was synthesized on the surface of the substrate by UV-assisted in-situ polymerization using modified Nano-TiO2 as the substrate, and conductive / UV-resistant composite fibers were obtained. The effects of the amount of ammonium persulfate, the concentration of hydrochloric acid and the amount of aniline on the conductivity of the conductive / UV-resistant composite fibers were discussed, and the preparation process was optimized. Surface resistance, UV resistance and scanning electron microscopy showed that the target fibers have good electrical conductivity and UV resistance, and at the same time proved that nano-TiO 2 exists in the target fibers.
