A superhydrophobic‐superoleophilic PVDF membrane is fabricated via an inert solvent‐induced phase inversion for effective separation of both micrometer and nanometer‐sized surfactant‐free and surfactant‐stabilized water‐in‐oil emulsions solely driven by gravity, with high separation efficiency (oil purity in filtrate after separation > 99.95 wt%) and high flux, which is several times higher than those of commercial filtration membranes and reported materials with similar permeation properties.
