Abstract
Various polymer surfaces, low density polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polymethyl methacrylate (PMMA), and polystyrene (PS), were gradually exposed to water vapor plasma along the sample distances. This treatment produced a continuous change in wettability and also hydroxyl group density on the polymer surfaces, as evidenced by water contact angle measurement and electron spectroscopy for chemical analysis (ESCA). The hydroxyl group gradient surfaces can be used to optimize protein. blood. or cell interactions with polymer surfaces.

플라즈마 방전 장치를 이용해 PE, PP, PET, PMMA, PS 등의 고분자 시료 표면에 수증기 분위기하에서 플라즈마 노출시간을 서서히 변화시켜 주었다. 이와같은 처리에 의해 고분자 시료 표면에서 친수성과 수산기 표면 밀도가 점 진 적으로 변한다는 것이 물 접촉각 측정과 ESCA분석 결과에 의해 확인되었다. 표면의 성질이 점진적으로 변하는 고분자 시료는 고분자 표면과 생체와의 상호반응 연구 및 의료용 고분자로서 응용하기 위한 최적 조건 정립에 매우 효율적이다.
