Abstract:
The efficient and rapid separation of oil from stabilized oil-in-water emulsions with micro/nanometer size is a global challenge. Owing to the low oil content in oil-in-water emulsions, separating the oil by simply controlling the surface wettability is difficult. Controlling the pore size of the membrane surface to achieve separation will lead to a sharp decrease in flux. Herein, inspired by cell membrane transportation, a hydrophilic/hydrophobic bifunctional Janus membrane for stable oil-in-water separation was prepared by simple surface polymerization and vapor diffusion.
Keywords:
bifunctional Janus membrane; demulsification function; oil-in-water emulsion separation; superhydrophobicity/super-oleophilicity; surface chemistry
