초록
과불소 에테르 화합물(PFPE)은 높은 접촉각 및 낮은 표면에너지, 우수한 윤활제 성질과 방오성의 특성을 가지고 있어 산업적으로 많은 관심을 받아왔다. 반면에, 합성단계의 복잡성과 위험성을 갖고 있어 많은 연구가 되어 오지 못했다. 본 연구에서는 과불소 폴리에테르 올리고머 형태의 새로운 실란화합물을 합성하고 19F-NMR 및 1H-NMR을 통하여 구조분석 하였다. 또한 코팅필름의 접촉각 및 흐름각, 내오염성 등 표면 특성을 조사하였다. 그 결과, 기존의 방오성 필름보다 낮은 흐름각과 우수한 내오염성의 특징을 보여 방오성 필름 코팅제로서 산업적 가능성을 확인하였다.
Perfluoropolyether(PFPE) has been widely applied in industry because of its very excellent properties of very high contact angle and low surface energy, good lubricant property and antifouling property. But the difficulty to synthesize PFPE has limited the research on this field. In this study, the novel silicon-containing oligomer with perfluoropolyether moiety was synthesized, and the structure was characterized by 19F-NMR and 1H-NMR. The surface properties of contact angle, sliding angle, and soil release property were investigated. The results show that PFPE in this study can be utilized as an anti-smudge coating material because it shows lower sliding angle and better soil release property than commercial products.
