摘要
为了研究不同防紫外线添加剂对PAN纳米纤维的影响,在聚合物PAN溶液中分别加入了TiO2与UV531,利用静电纺丝技术制备了PAN仪等仪器对比分析了纯PAN、PAN/UV531、PAN严重,表面会有TiO2颗粒聚集;红外光谱图显示PAN说明TiO2与UV531的加入并未改变聚合物PAN的分子基团结构;添加防紫外线的TiO2与UV531后,PAN纳米纤维膜的防紫外线性能有了卓越的提升,添加剂的含量越高,紫外线防护性能越好,对UVA和UVB的透射率越小。
To study the influence of different UV additives on PAN nanofibers, TiO2 and UV531 are added into PAN solution, PAN ultraviolet(UV) protective properties are comparatively analyzed by using scanning elect/r on microscopy(S/EM), UV and visible smaller, the standard deviation of fiber diameter is less, but wit/h the increase/o f TiO2 content, aggregation becomes more on the surface.indicated that additives TiO2 and UV531 will not change the interior radical structure of PAN. The addition of TiO2 and UV531 can enhance UV-protection performance. With the increase of TiO2 and UV531 content, the UV-protection performance is better while the transmittance of UVA and UVB decreases.
