摘要
采用溶胶凝胶法制备纳米二氧化钛(TiO2,利用聚多巴胺(PDA)的高黏附性对聚丙烯纤维表面进行修饰,再将纳米Ti(X与PP纤维表面的PDA结合,制备抗老化聚丙烯纤维。结果表明:制备的纳米TiO,被成功改性到PP纤维表面,并在PP纤维表面形成了均匀、致密,且牢固结合的纳米TiO2薄膜层。经长时间紫外光照射后,改性后的PP/PDA/TiO2纤维的强力比原PP纤维有明显提高,且强力下降速率明显降低;改性后PP/PDA/TiO2纤维的抗紫外光老化能力也有显著提升。
In this paper, nano-titanium dioxide (nano-TiO2) is prepared by sol-gel method. The surface of polypropylene fiber is modified by high adhesive polydopamine (PDA), and nano-TiCh is combined with PDA on PP surface to prepare anti-aging acrylic fiber. The experimental results show that the prepared nano-TiO2 is successfully grafted onto the surface of PP fiber, and a uniform, compact and firmly bonded nano-TiO2 film layer is formed on the surface of PP fiber. After long-term ultraviolet irradiation, the strength of modified PP/PDA/TiO2 fiber is significantly higher than that of PP fiber. The anti-UV aging ability of modified PP/PDA/TiO2 fiber is significantly higher than that of PP fiber.
