Research progress in PLA⁃based oil⁃water separation materials

doi:10.19491/j.issn.1001-9278.2022.09.024

Abstract

Abstract:

A new type of poly（lactic acid）（PLA） oil⁃water separation material with super hydrophobic， super lipophilic and biodegradable characteristics was introduced. The research and application status of pure PLA and PLA⁃based oil⁃water separation materials were compared and analyzed. The preparation of oil⁃water separation films using PLA as a main raw material or matrix material not only can achieve an ideal oil⁃water separation effect， but also can be recycled for many times after post⁃treatment. The PLA⁃based oil⁃water separation material can be considered as one of the ideal oil⁃water separation materials at present. Finally， the future development direction of PLA in the field of oil⁃water separation was proposed.

Key words: poly（lactic acid）, oil?water separation, biodegradability, sustainable oily waste water treatment
