초록
본 연구의 목적은 대기압 플라즈마 처리된 평판형 폴리프로필렌(polypropylene, PP) 필름 표면 위에 폴리비닐피롤리돈(poly(N-vinyl-2-pyrrolidone), PVP)을 그래프트 공중합시키기 위한 최적 조건을 찾는데 있다. 대기압 플라즈마 처리 조건은 RF power 200W, Ar 유속 6 LPM, 처리시간 30초, 처리 후 노출시간은 5분으로 고정하였다. 그래프트 공중합에서는 중합 시간, 중합 온도, 비닐피롤리돈(N-vinyl-2-pyrrolidone, NVP) 농도의 조건을 각각 달리하여 표면 그래프트도의 변화를 조사하였다. 그 결과, 중합 시간 6시간, 중합 온도 90 ℃, NVP 농도 40%에서 가장 높은 그래프트도를 나타내었다. ATR-FTIR, X-ray photoelectron spectroscopy(XPS), SEM 분석을 통해서도 PVP의 도입을 확인할 수 있었다.
The objective of this study is to investigate optimum reaction conditions for the grafting of poly(Nvinyl-2-pyrrolidone) (PVP) onto the surface of plasma-treated polypropylene film. The plasma treatment conditions were fixed as 200 W rf power, 6 LPM Ar flow rate, 30 sec treatment time, and 5 min exposure time after treatment. For graft copolymerization, we investigated the change of grafting degree with respect to reaction time, reaction temperature and N-vinyl-2-pyrrolidone concentration. Maximum grafting degree was obtained at the conditions of 6 h reaction time, 90 ℃ reaction temperature, and 40% N-vinyl-2-pyrrolidone concentration. The introduction of PVP was confirmed by ATR-FTIR, XPS, and SEM analysis.
Keywords:plasma-induced graft copolymerization;poly(N-vinyl-2-pyrrolidone);polypropylene.
