Glomerulus Inspired Charged Nanofibrous Membrane for High‐Efficient Micro/Nano‐Emulsion Separation

Abstract Separating oil‐in‐water micro/nano‐emulsions efficiently is a difficult task. Because of the wide droplet size distribution and high stability, superwetting membranes that utilize “size‐sieving” separation mechanisms often face challenges to balance separation efficiency and flux, especially when dealing with nano‐emulsions composed containing extremely small droplet sizes. In this study, a glomerulus‐inspired multilayer nanofibrous membrane (GIM) is developed. The membrane is fabricated via sequential electrospinning with a gradient pore structure that gradually decreases from top to bottom. In addition, a hydrophilic surface coating with mixed charges is applied to the nanofibrous membrane, creating…
