Delamination-Free In-Air and Underwater Oil-Repellent Filters for Oil-Water Separation: Gravity-Driven and Cross-Flow Operations

Separating oil-water mixtures is critical in a variety of practical applications, including the treatment industrial wastewater, oil spill cleanups, as well purification petroleum products. Among various methodologies that have been utilized, membranes are most attractive technology for separating emulsions. In recent years, selective wettability attracted particular attention separations. The membrane surfaces with hydrophilic and in-air oleophobic demonstrated enhanced effectiveness separations comparison underwater membranes. However, developing surface not trivial task. coating delamination process challenge when applying these Inspired by above, this study we utilize poly(ethylene glycol)diacrylate (PEGDA) 1H,1H,2H,2H-heptadecafluorodecyl acrylate (F-acrylate) to fabricate on filter. We methacryloxypropyl trimethoxysilane (MEMO) an adhesion promoter enhance filter demonstrates robust repellency preventing fouling. Utilizing filter, gravity-driven continuous surfactant-stabilized emulsions demonstrated. Finally, demonstrate can be reused multiple times upon rinsing further
