摘　　要：为制备具有防电磁辐射、防紫外线功能的纳米纤维膜,文章在聚丙烯腈(PAN)溶液中加入纳米银颗粒(AgNPs)和紫外线吸收剂UV531,利用静电纺丝技术制备纯PAN和PAN/AgNPs、PAN/AgNPs/UV531复合纳米纤维膜,测试分析纳米纤维膜的微观形貌、红外光谱、防电磁辐射性能、紫外线防护性能和紫外线吸收性能。结果表明:AgNPs和UV531的加入没有改变PAN的大分子结构;将质量分数分别为1.2%、0.5%的AgNPs和UV531加入纯PAN溶液中,制备得到的PAN/AgNPs/UV531复合纳米纤维膜,纤维直径较小且分布较均匀,防电磁辐射功能和紫外线防护功能优良,可用于开发防电磁辐射/防紫外线纳米纺织品。To prepare nanofiber membranes with electromagnetic radiation protection and ultraviolet protection function,silver nanoparticles(AgNPs)and ultraviolet absorbent UV531 were added into polyacrylonitrile(PAN)solution.Pure PAN,PAN/AgNPs and PAN/AgNPs/UV531 composite nanofiber membranes were prepared by electrostatic spinning technology.The micromorphology,infrared spectrum,electromagnetic radiation protection,ultraviolet protection and ultraviolet absorption properties of the nanofiber membrane were tested and analyzed.The results showed that the addition of AgNPs and UV531 did not change the macromolecular structure of PAN.For the PAN/AgNPs/UV531 composite nanofiber membrane which was prepared by adding AgNPs and UV531 with mass fraction of 1.2%and 0.5%respectively into pure PAN solution,the fiver diameter was small and the distribution was uniform.The functions of electromagnetic radiation protection and ultraviolet protection were excellent,which could be used in the development of nanotextiles with the function of electromagnetic radiation protection and ultraviolet protection.
