초록
본 연구에서는 아크릴계 고분자의 소수성 차이에 따른 막 모폴로지 변화를 조사하였다. 막은 poly(methyl methacrylate)(PMMA), poly(ethyl methacrylate)(PEMA), poly(butyl methacrylate)(PBMA), poly(isobutyl methacrylate)(PIBMA) 및 이들의 블렌드를 사용하여 습식 상 역전 방법으로 제조하였다. 상대적으로 소수성이 적은 PMMA와 PEMA는 channel-like 형태의 막 구조를, 소수성이 큰 PBMA와 PIBMA는 finger-like 형태의 막 구조를 보여주었다. 이러한 막 구조의 변화는 polymer-rich 상의 고상화 과정에서 속도론적 차이가 있었기 때문이었다. 이성분 블렌드 막의 구조는 주 성분 고분자에 의해 결정되었다.
In this work, the effect of the hydrophobicity of acrylic polymers on the membrane morphology was investigated. The membranes were prepared with poly(methyl methacrylate) (PMMA), poly(ethyl methacrylate) (PEMA), poly (butyl methacrylate) (PBMA), poly(isobutyl methacrylate), and their blends using the wet phase inversion method. PMMA and PEMA having a relatively less hydrophobicity formed the channel-like structure, whereas PBMA and PIBMA having more hydrophobic units formed the finger-like structure. These morphological changes were attributed to differences in the solidification process of the polymer-rich phase determined by the polymer/solvent/nonsolvent ternary phase diagram. The membrane structures of the blends were controlled by the main component of their blends.
