摘要：

Acrylic monomers were grafted on the surface of commercial polyamide membranes using plasma polymerization and ultraviolet irradiation techniques. Graft reaction was confirmed by X-ray photoelectron spectra. Grafting yield increased with plasma and ultraviolet exposure time. Permeation of riboflavin through graft membranes was investigated. Poly(acrylic acid-g-amide) membranes showed a decrease in permeability of riboflavin at pH 4-5, while poly(methacrylic acid-g-amide) membranes exhibited decreased permeability at pH 6-7 regardless of the grafting methods. N-isopropylacrylamide-grafted polyamide membrane showed a temperature-dependent permeation of riboflavin.
