As an alternative to polymer membranes, ultrathin free‐standing single‐walled carbon‐nanotube network films are used to realize oil/water separation with ultrahigh flux. The films with tunable thickness of the tens of nanometer scale can effectively separate both micrometer and nanometer‐sized surfactant‐free and surfactant‐stabilized water‐in‐oil emulsions with a flux 2–3 orders of magnitude higher than commercial filtration membranes with similar separation performance.
