摘要
利用射频磁控溅射在聚氨酯纳米纤维膜表面溅射聚四氟乙烯,制备了一种新型的防水透湿薄膜。通过原子力显微镜、扫描电镜、接触角测量仪等对薄膜的表面形貌、浸润性以及透湿性进行了研究。结果表明:溅射后,聚氨酯纳米纤维膜表面出现双重粗糙度,纤维表面出现几十到几百纳米的的小岛型颗粒;薄膜表面的接触角增大至128.6°,5min后接触角只减小了1.5°;透湿量受溅射的影响较小,可达到6760g/m2·24h。
A novel waterproof and breathable membrane was prepared by RF magnetron sputtering,polytetrafluoroethylene（PTFE）was sputtered onto the surface of polyurethane（PU）nanofibrous membrane substrate.The atomic force microscope（AFM）,scanning electron microscope（SEM）,static contact angle testing apparatus and moisture measuring instrument were employed to investigate the surface morphology,wettability and water vapor permeability of the membrane.The results indicated that double roughness occurred on the surface of membrane after sputtering,massive island shaped particles with the diameter from dozens to hundreds of nanometers formed on the fibrous surface.The surface contact angle of the membrane increased to 128.6°and reduced by 1.5°after 5min.The moisture transmission affected by sputtering was minor,can approach 6760g/m2·24h.
