Research progress of poly lac tic acid oil-water separation materials.

The special wetting surface structure for oil-water separation is introduced this paper, including superhydrophobic-superoleophilic surfaces, superhydrophilic-underwater superoleophobic surfaces and su- perhydrophilic-superoleophobic surfaces. The preparation method and properties of PLA oil-water separation materials are summarized, such as impregnation, spraying, electrostatic spinning, phase separation, grafting, supercritical CO2 foaming and 3D printing. Future development trend is prospected. [ABSTRACT FROM AUTHOR]
