Abstract: A method of fabricating high permeable polyamide composite nano-filtration membrane is provided to produce the membrane with remarkably improved water permeation while retaining high rejection of bi-valent salts and low rejection of mono-valent salts by precipitating porous supporter into multi-functional amine solution and isoparaffin organic solution in turns. The method comprises the steps of: immersing a porous supporting material in an aqueous solution containing hydrophilic polymer and removing excess amine from the precipitated supporting material; conducting interfacial polymerization of the treated supporting material by immersing the material in isoparaffin organic solution; and immersing the polymerized supporting material in a weak alkaline solution after drying the supporting material. The aqueous solution includes hydrophilic polymer having vinyl group and multi-functional amine compound. The isoparaffin organic solution contains multi-reactive acyl halide.

Abstract: 본 발명은 초투과유량 폴리아미드 나노복합막의 제조방법에 관한 것으로서, 더욱 상세하게는 다공성 지지체를, 다관능성 아민화합물 0.1 ∼ 3 중량%와 친수성 고분자 0.1 ∼ 3 중량%의 농도로 함유한 수용액과, 다반응성 아실할라이드 0.01 ∼ 0.3중량%의 농도로 함유된 C
8 ∼ C
12 의 이소파라핀계 유기용액에 순차적으로 침지시켜 계면중합하는 공정을 수행하여, 2가 염의 배제율은 높게 유지되고 1가 염배제율은 낮게 유지되면서, 종래에 비해 투수율은 월등히 향상된 폴리아미드 나노복합막의 제조방법에 관한 것이다.
