电纺纳米纤维膜

Abstract(#br)Superhydrophobic electrospun nanofibrous membranes (ENMs) with a fully interconnected porous web structure and high void volume fraction have been proposed for membrane distillation (MD). This study describes a novel and facile design strategy for the fabrication of superhydrophobic and self-cleaning polysulfone-polydimethylsiloxane (PSU-PDMS) ENMs for direct contact membrane distillation (DCMD) via electrospinning PSU nanofibers followed by PDMS coating and cold-press post-treatment.

开发集自修复、自清洁、高效分离功能于一体的分离材料，对于含油废水和溢油的修复具有重要意义和挑战性。本工作发展了一种制备具有自修复超疏水性能的聚酰亚胺( PI )纳米纤维膜的简易方法。所设计的膜对一系列油水混合物和油包水乳液具有显著的分离效率。此外，由于PI膜与聚二甲基硅氧烷/十八胺( PDMS / ODA )涂层的协同环境稳定性，该膜在恶劣环境出良好的适应性。特别令人感兴趣的是，所制备的膜具有优异的自愈和自清洁能力，具有多功能集成。这些特性使膜成为一种在现实环境中高效油水分离的理想分离材料。
