Study on the Superhydrophobic Effect of Polymer Pattern Film

초록

Superhydrophobic surfaces, with contact angle about 150(degrees) 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 150(degrees) . Special pattern structures of honeycomb and pillar honeycomb mor-phology were achieved using UV-Imprint lithography process (UV-ILP) on the bulk polyethylene terephthalate film. In conclusion, superhydrophobic pattern film, with contact angle about 150(degrees) 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.
