Abstract

다공성 지지체 층에 부착된 선별층을 갖는 복합막 형성 방법이 기술되어 있다. 당해 방법은, 0.01 내지 30중량%의 중합체를 함유하는 수성 중합체 용액을 용액 및 블랭킷 유체의 경계상에서 중합체 용액 표면 위에서 중합체 필름 형성에 충분한 조건하에서 조사하여 선별층을 형성시킴을 포함한다. 바람직한 중합체는 하이드록시에틸메타크릴레이트/비닐벤질디메틸 설포늄/메타크릴산 터폴리머이다.A method of forming a composite membrane having a selective layer attached to a porous support layer is described. The method comprises irradiating an aqueous polymer solution containing 0.01-30% by weight of polymer under conditions sufficient to form a polymer film on the polymer solution surface on the boundary of the solution and the blanket fluid to form a selection layer. Preferred polymers are hydroxyethyl methacrylate / vinylbenzyldimethyl sulfonium / methacrylic acid terpolymers.
