Liquid-based Janus porous membrane for convenient liquid-liquid extraction and immiscible oil/water separation

Abstract

The liquids separation relevant to the environmental protection and chemical industry is guided by the solid porous membranes or liquid-based system. However, the solid porous membranes are plagued with the issues: persistent fouling problems, inability to self-heal, and poor stability, while the liquid-based systems are limited to the low-pressure applications and the perfluorinated fluids. Here, we provide a novel liquid-based Janus porous membrane (LBJPM) system, which can be infused by the universal liquids (water and immiscible organic solvents) at the same time forming a stable liquid infusion-interface to repel the immiscible organic solvents and water respectively. The LBJPM system, possession the self-gating, improved interfacial floatability, and outstanding stability, can be used in some practical applications: liquid-liquid extraction and ultrafast immiscible oil/water separation with antifouling behavior.
