계면중합조건에 따른 복합막의 물성 변화

The Change of Properties of reverse Osmosis Thin Film Composite Membrane according to Preparation Conditions

이동진, 민병렬

초록

역삼투복합막의 박막으로 사용되고 있는 polyamide의 성능을 용질투과방식과 연관하여 이론적으로 고려하고 단량체 및 제조 조건을 변화시켜 계면중합을 통해 제조하여 봄으로써 이의 검증을 시도하였다. 제조된 고분자는 중합조건에 따라 물질 구성의 변화를 보여 주었으며, 이는 이론적으로 제시한 값의 범주에 속하였다. 또한 이에 따라 막성능에서도 큰 영향을 발휘한 바, 용매의 변화, 수용상 및 유기상 단량체의 농도 비율에 따라 고분자의 함유성분의 변화를 가져왔다.

The theoretical and experimental analysis on polyamide used for reverse osmosis thin-film composite membrane had been conducted. The physicochemical propertise of polyamide recipes which depends on kinds of monomer, solvents and polymerization time. These properties and performance as a reverse osmosis membrane had been calculated by group contribution method. The experimental results has the same trends with theoretical preview.
