Research progress of preparation of environmental stimuli-responsive smart membrane materials by using ATRP techniques

Poly(N-isopropylacrylamide) (PNIPAM) has both thermo- and ethanol concentration- responsive performance as a common smart material. Based on the PNIPAM polymer，the research progress of preparations of environmental stimuli-responsive smart membrane materials by using ATRP method，including thermo-responsive，dual pH-/thermo-responsive，ethanol- concentration-responsive，and some other responsive membranes，was introduced and discussed. The thermo-responsive smart membranes were PNIPAM homopolymer type grafted membranes，the thermo-/pH-responsive smart membranes were the PNIPAM and pH responsive block copolymer type grafted membranes，and the ethanol-concentration-responsive smart membranes were the PNIPAM random copolymer type grafted membranes. Other type smart membranes were the chiral recognition and ion recognition smart membranes. Based on the advantages of ATRP methods discussed in this paper and the wide application in the fields of membrane modification research，ATRP method would play an important role in environmental stimuli-responsive smart membrane preparation，and industrial application of this type of membrane.
