摘要
利用静电纺丝制备具有良好纤维形态及优异力学性能的聚甲基丙烯酸甲酯、聚氨酯和氧化锌(PMMA/PU/ZnO)复合纳米纤维膜,采用等离子技术对复合纳米纤维膜进行亲水性修饰,并探究其对染料废水的光催化降解性能。本文对PMMA/PU/ZnO复合纳米纤维膜的微观形态结构进行详细表征,并对其亲水性能、力学性能及重复使用性能予以测试。结果表明,在300 W汞灯照射条件下,经等离子处理的PMMA/PU/ZnO复合纳米纤维膜对亚甲基蓝、罗丹明B和活性红的降解率分别为85%、59%和52%,经3次重复使用后仍具有良好的降解性能。
The polymethyl methacrylate,polyurethane and zinc oxide(PMMA/PU/ZnO)blend nanofibrous membrane with ideal fiber morphology and excellent mechanical property was prepared by electrospinning technique.Then,the hydrophilicity of blend nanofibrous membrane was improved by the plasma technology,furthermore,the photocatalytic performance of the nanofibrous membrane was analyzed.In addition,the surface microstructure of PMMA/PU/ZnO blend nanofibrous membrane was characterized in detail,and its hydrophilic property,mechanical property and reusability were measured in this article.The results showed that the surface modified PMMA/PU/ZnO blend nanofiberous membrane has a degradation rate of 85%,59%and 52%for methylene blue,rhodamine B and reactive red under illumination by 300 W Hg lamp,and the nanofibrous membrane could still maintain fine degradability after 3 times of reuse.
