Abstract
Porous polyurethane(PU) membranes were prepared by phase inversion method. Surfaceof PU membrane was reacted with five monomers using ceric ammonium nitrate(CAN). Five monomers include acrylamide, methacrylamide, acrylic acid and N.N-diethylaminoethyl methacrylate. Permeation behavior of riboflavin was observed using these graft membranes. Poly(acrylamide-g-urethane) and poly(methacrylamide-g-urethane) membranes did not show the pH sensitivity for riboflavin permeation while poly(acrylic acid-g-urethane), poly(methacrylic acid-g-urethane) and poly(N,N-diethylaminoethyl methacrylate-g-urethane) membranes showed a decrease in permeability of riboflavin as pH increased.

폴리우레탄 다공성막을 상전이법으로 제조하고 막표면에 5가지 단량체들을 ceric ammonium nitrate(CAN)을 사용하여 크라프트반응시켰다. 사용한 단량체들은 아크릴아미드, 메타크릴아미드, 아크릴산, 메타크릴산 및 디에틸아미노에틸메타크릴레이트이다. 이들 그라프트막을 통해 리보플라빈의 투과거동을 살펴보았다. 아크릴아미드와 메타크릴아미드가 그라프트된 경우에는 pH에 대한 투과도변화가 나타나지 않은 반면 아크릴산, 메타크릴산, 디에틸아미노에틸메타크릴레이트가 그라프트된 경우에는 pH증가에 따라 투과도가 감소하였다.
