Abstract

Superhydrophobic surfaces, with contact angle about 150o have been widely studied and used in research and industrial fields owing to their fabulous physical properties, such as water repellency, lubricity, self-cleaning, antifouling and so on. Designing suitable form of pattern combined with chemical compositions of the surface, is crucial for preparing superhydrophobic surfaces. In this study, mixing of trimethylsilyl group and various polymer pattern film were tried in an effort to improve water-contact angle about 150o. Special pattern structures of honeycomb and pillar honeycomb morphology were achieved using UV-Imprint lithography process (UV-ILP) on the bulk polyethylene terephthalate film. In conclusion, superhydrophobic pattern film, with contact angle about 150o was fabricated and cell viability was confirmed more than 80%. Also, we investigated various properties of polymer pattern film such as morphology, adhesion and water repellency.


접촉각이 150o 수준을 가지는 초발수성의 표면은 발수성, 윤활성, 자기세정성, 방오성 등과 같은 우수한 특성으로 인하여 많은 산업 분야에서 연구되어 오고 있다. 다양한 패턴 형태를 설계하고 표면의 화학 조성물과 결합하는 것은 초발수성 표면 특성을 구현하는데 있어 중요한 부분이다. 본 연구에서는 접촉각을 개선하기 위해 trimethylsilyl group의 혼합과 다양한 고분자 패턴을 설계하여 제작하였다. Bulk polyethylene terephthalate 필름 위에 UV-imprint lithography process(UV-ILP)을 사용하여 육각과 pillar honeycomb 패턴 구조를 가지는 고분자 패턴 필름을 제조하였다. 결론적으로 접촉각이 약 150°인 초발수성의 패턴 필름을 제작하였고, 제조된 패턴 필름에서 80% 이상의 세포 생존율을 가짐을 확인하였다. 또한 고분자 패턴 필름의 형상, 밀착성 및 발수성 같은 다양한 특성들을 조사하였다.
