摘要

为有效处理含油废水,开发具有可切换超润湿性的先进膜引起了广泛关注。然而,通过简单的方法设计和制造这种膜仍面临挑战。本研究提出了一种基于微/纳米结构多孔表面和表面化学成分重组设计可切换超润湿膜的新策略。采用一步非溶剂诱导相分离法,将商用两亲聚合物聚酰胺-酰亚胺(Torlon)制成具有分层表面结构的多孔对称膜。利用两亲性聚合物的表面重组能力和分层多孔结构,制成的膜具有优异的空气超亲和性、水下超疏油性和油下超疏水性。利用这些特性,可通过重力驱动工艺实现水包油、油包水和原油/水乳状液的超高渗透率和分离效率,无需外部能源。此外,这种膜还具有出色的防污和自清洁性能,可在多次循环中保持稳定运行。这项工作为下一代可切换超润湿膜提供了一种创新和可扩展的方法,在含油废水处理及其他领域具有广泛的应用潜力。

Hierarchically Structured Porous Polyamide-Imide Membrane for Switchable Emulsion Separation

Hierarchically Structured Porous Polyamide-Imide Membrane for Switchable Emulsion Separation
The development of advanced membranes with switchable superwettability has attracted considerable attention for the efficient treatment of oily wastewater. However, challenges persist in designing and fabricating such membranes through straightforward methods. In this study, a novel strategy is presented to design switchable superwettable membranes based on micro/nano-structured porous surfaces and surface chemical composition reorganization. A commercial amphiphilic polymer, polyamide-imide (Torlon), is fabricated into a porous symmetric membrane with a hierarchical surface structure using a one-step non-solvent-induced phase separation method. By leveraging the surface reorganization capability of amphiphilic polymers and the hierarchically porous structure, the resulting membranes demonstrate exceptional superamphiphilicity in air, underwater superoleophobicity, and underoil superhydrophobicity. These properties enable ultrahigh permeance and separation efficiency for oil-in-water, water-in-oil, and crude oil/water emulsions through a gravity-driven process, eliminating the need for external energy. Furthermore, the membranes exhibit excellent antifouling and self-cleaning performance, maintaining stable operation over multiple cycles. This work provides an innovative and scalable approach to next-generation switchable superwettable membranes with broad potential applications in oily wastewater treatment and beyond.
