Superhydrophilic and underwater superoleophobic poly (acrylonitrile-co-methyl acrylate) membrane for highly efficient separation of oil-in-water emulsions
Demulsification-type Janus membranes are constructed with controllable asymmetric configurations for highly efficient separation of oil-in-water emulsions. A mechanism is proposed as demulsification followed by rapid unidirectional oil transportation.
Purification of highly emulsified oily wastewater is of significance but challenging due to the critical limitations of low efficiency and serious membrane blocking. Herein, inspired by the desert beetle's ability...
