The purpose of this study is to grasp the change of modern space concept and analyze how to adopt and embody the change in modern fashion. The study researched wearer's costume space and analyzed space shown in supermodern fashion design by classifying it into response to non-space, allowance of wearer-based space, scientific space of architectural skill and embodiment of space image. As a study method, literature and study material of sociology, anthropology, fashion sociology and design field were referred. For picture data of supermodern fashion work, specialized book, designer, brand collection material and internet site pictures were collected and analyzed. The study result shows the following features of fashion design space embodiment corresponding to the change of supermodern environment. First, supermodern design secures closet space like pocket for portable objects and uses design space in order to provide the space for convenience of movement. Second, supermodern design creates wearer-based independent space in order to secure person's physical and mental stability in city environment. Third, supermodern design uses space scientifically from the aspect of detail and shape by applying space of architectural skill to space. Fourth, supermodern design shows aesthetic feature that embodies interpretation of space by conceptualizing space image and using fashion.

본 연구에서는 pellet 상태의 polyetherimide (PEI)를 carbon tetrachloride(CCl4)와 1 ,2-dichloro-ethane (DCE) 의 부피비 5:1 하에서 PEI를 불균일한 상태로 유지시키고, chlorosulfonic acid (CSA)를 이용하여 PEI의 표면을 sulfonation 시킴으로써 , 음이온성을 띠며 친수성이 향상된 sulfonated polyetherimide (SPEI)를 제조하였다. 불균일한 상태가 유지되면서 가장 적합한 sulfonation 반응조건은 PEI: CSA 의 1 : 1 mole ratio, 온도 10℃, 3 시간이었다. 이온교환용량이 0.2~1.2meq/g을 갖는 SPEI를 합성할 수 있었고, FT-IR 측정을 통하여 sulfonic acid peak가 1020cm-1 와 1170cm-1부근에서 관찰되었다. 분자량 분포는 sulfonation을 시킴으로써 좀 더 넓게 나타났고, 접촉각 측정을 통하여 친수성이 향상되었음을 확인하였다.

Sulfonated Polyetherimide 막은 pore 형성을 위한 polyvinylpyrrolidone 과 저비점 용매 dichloromethane을 첨가하여 투과성능을 최적할 수 있었다. SPEL 막의 친수성은 단백질등의 투과시 모든 pH 범위에서 막 오염을 효과적으로 억제할 수 있으며, 도입된 sulfonic acid group의 음이온성으로 인하여 동일한 전하의 용질을 쉽게 분리할 수 있었다.
