To solve the problems of membrane material tolerance and membrane fouling, a micro/nano hierarchial structure with low surface energy was constructed above the exterior surface of a ceramic hollow fiber membrane using ZnO nanorod arrays and 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PDTS) coatings, which make it superhydrophobic and self-cleaning. The surface morphology, chemical functional groups, and water contact angel of the modified membranes were identified. The results show that large quantity of ZnO nanorods possess desirable characteristics (i.e. superhydrophobicity, exceptional thermal and mechanical stability, and water contact angle of 160.12°) were detected on the ceramic membrane. The novel membrane shows excellent self-cleaning performance and good desalination ability in the utilization of vacuum membrane distillation (VMD) system for high-salinity water desalination.

ZnO纳米棒阵列制备的超疏水陶瓷中空纤维膜用于高盐度水脱盐

为了解决膜材料耐受性和膜污染的问题,使用ZnO纳米棒阵列和1H,1H,2H,2H-全氟癸基三乙氧基硅烷(PDTS)在陶瓷中空纤维膜的外表面上方构建了具有低表面能的微/纳米分层结构)涂料,使其具有超疏水性和自洁性。鉴定了改性膜的表面形态,化学官能团和水接触角。结果表明,大量的ZnO纳米棒具有令人满意的特性(在陶瓷膜上检测到超疏水性,出色的热和机械稳定性以及与水的接触角为160.12°。该新型膜在利用真空膜蒸馏(VMD)系统进行高盐度水脱盐中表现出优异的自清洁性能和良好的脱盐能力。
