摘要：

为制备防紫外线功能的纳米纤维制品，选用聚丙烯腈（PAN）和紫外线吸收剂UV531 作为原料，利用静电纺丝方法制备了纯PAN 和PAN 复合纳米纤维膜，用扫描电子显微镜、紫外线透反射分析仪等分析了纳米纤维的微观形貌、化学性能、紫外线防护性能等。结果表明：紫外线吸收剂的加入有效地减小了复合纳米纤维的直径，纯PAN和PAN 复合纳米纤维膜的红外光谱均表现出ＰＡＮ的特征峰，说明紫外线吸收剂的加入没有改变PAN的内部结构；紫外线吸收剂的加入提升了复合纳米纤维膜的紫外吸收性能和紫外防护性能，随着紫外线吸收剂含量的增加，紫外吸收值和紫外防护因子越大，而紫外线的透射率越小；因此，PAN复合纳米纤维膜是非常优异的防紫外线制品。

Abstract:

In order to prepare functional nanofiber products, polyacrylonitrile (PAN) and UV absorber (UV531) were chose as raw materials to prepare pure PAN and mixed PAN/UV531 nanofibrous membrane by electrospinning. The morphologies, chemical and UV-protectionl performance were analyzed using scanning electron microscop, Fourier transform infrared and UV transmittance analyzer. The results show that the presence of UV531 decreas the diameter of PAN/UV531. Infrared spectra of PAN and composite nanofibers all express the characteristic peaks of PAN, indicating that the addition of UV531 does not change the interior structure of PAN. In addition, the addition of UV531 enhances the UV-absorptoin perfomance and UV-protection performance, and with the increasing of UV531 content, the UV-absorption value and UV pretection factor (UPF) increased, while the transmittance of UVA and UVB decreased. Hence, the PAN/UV531 composite nanljibers are excellent anti-ultraviolet products.

Key words: polyacrylonitrile, ultrabiolet absorbent, nanofiber, UV-protection performance
