摘要：

Graft copolymerization of spiropyran-containing methacrylate (SPMMA) and acrylamide (AM) onto the surface of a porous polymer membrane was carried out. The permeability of the graft membrane varied with ultraviolet (UV)- or visible-light irradiation. It was found that the change by UV-light irradiation of the permeability of the H2O/CH3OH mixture through the SPMMA/AM-grafted membrane is related to the change by UV-light irradiation of the solubility, i.e., the chain extension, of the graft copolymer in the mixed solvent. When the free SPMMA/AM copolymer becomes insoluble in the H2O/CH3OH mixture by UV-light irradiation, the permeability of the H2O/CH3OH mixture through the SPMMA/AM-grafted membrane is increased.
