Chelation-directed interface engineering of in-place self-cleaning membranes

Proceedings of the National Academy of Sciences, Год журнала: 2024, Номер 121(11)

Опубликована: Март 4, 2024

Water-energy sustainability will depend upon the rapid development of advanced pressure-driven separation membranes. Although energy-efficient, water-treatment membranes are constrained by ubiquitous fouling, which may be alleviated engineering self-cleaning membrane interfaces. In this study, a metal-polyphenol network was designed to direct armorization catalytic nanofilms (ca. 18 nm) on inert polymeric The chelation-directed mineralized coating exhibits high polarity, superhydrophilicity, and ultralow adhesion crude oil, enabling cyclable oil-in-water emulsion separation. in-place flux recovery rate exceeded 99.9%, alleviating need for traditional ex situ cleaning. nanoarmored exhibited 48-fold 6.8-fold figures merit regeneration compared control simple hydraulic cleaning, respectively. Precursor interaction mechanisms were identified density functional theory calculations. Chelation-directed offers promise sustainable applications in catalysis, biomedicine, environmental remediation, beyond.

Abstract Oil leakage and discharge of industrial organic solvents are the main reasons for oily wastewater. The separation oil/water emulsions has been a global challenge due to small particle size their stabilities. An effective method is needed resolve these issues. Superwettability membrane demonstrated high efficiency, fast speed, low energy consumption, good scalability, easy operation, recyclability. In essence, special wettability material mainly determined by two factors: chemical compositions surface morphology. Herein, in this review, development membranes discussed including different preparation methods, preparation, such as superhydrophobic/super lipophilic, superhydrophilic/underwater superoleophobic, superlipophilic/superhydrophobic under oil, smart with switchable wettability, self‐healing or self‐cleaning property. representative works each part introduced, focusing on innovations performance membranes. Finally, challenges future directions field also described.
