Abstract

본 발명은 복합반투막의 제조방법에 관한 것으로, 특히 분자량 수천에서 수만 정도의 용질을 포함하고 있는 저분자량 혼합물의 막분리에 적용이 가능한 복합반투막의 제조방법에 관한 것이다.The present invention relates to a method for producing a composite semipermeable membrane, and more particularly, to a method for preparing a composite semipermeable membrane which can be applied to membrane separation of a low molecular weight mixture containing thousands to tens of thousands of solutes in molecular weight.

본 발명에서는 폴리에틸렌이민과 다관능 가교제의 혼합가교제 용액을 다공성 지지체상에서 가교반응을 시켜, 그 다공성 지지체상에 반투성의 치밀층을 형성시킴으로써 저분자량 혼합물의 분리유용한 복합반투막의 제조방법을 제공한다.The present invention provides a method for producing a composite semipermeable membrane useful for separating low molecular weight mixtures by crosslinking a mixed crosslinker solution of polyethyleneimine and a polyfunctional crosslinking agent on a porous support to form a semipermeable dense layer on the porous support.

본 발명에 의한 복합반투막은 선택분리성도 우수하고 투과성도 뛰어나 저압에서도 사용이 가능하다.The composite semipermeable membrane according to the present invention is excellent in selective separation and excellent in permeability and can be used even at low pressure.
