本研究使用低表面能高分子：氧代氮代苯并環己烷與光觸媒材料；TiO2奈米粒子組成高分子奈米薄膜。在條件70% 氧代氮代苯并環己烷與30% 二氧化鈦在210℃聚合2小時之薄膜，能獲得超疏水表面薄膜並能在紫外光催化下使表面產生吸附力增加。藉由AFM接觸式探針測得紫外光照射前吸附力為0.72nN而照射後提升為5.76nN，此吸附力改變足以將原本水之滾動角從 4° 增加到 60° 以上仍未滾動，如此對水滴吸附力讓我們能應用於液體的微量傳輸上。在80% 氧代氮代苯并環己烷與20% 二氧化钛在270℃聚合2小時之薄膜，能在光催化後從 80°到 0°特性並可以不斷的光催化和真空烘乾程序使表面從親疏水間轉換。

Benzoxazine is used recently to form a superhydrophobic surface without halogen element. Titanium dioxide (TiO2) exhibiting hydrophilic and photocatalytic properties is known as a self-cleaning material. We attempted to hybridize both Benzoxazine and TiO2 nanoparticles with various weight ratios to include both functions of hydrophobic and self-cleaning in one material.
The water contact angle of benzoxazine hybrid material containing 20% titanium dioxide after 270℃ polymerization decreased from 80° to 0°under UV irradiation. The contact angle returned from 0° to 80° after drying it in vaccum oven. This behavior was defined as the UV responsive property for hydrophilic and hydrophobic after repeating the process cyclically. The benzoxazine hybrid material with UV responsive property for hydrophilic and hydrophobic could apply usefully as a self-cleaning material. However, the UV responsive behavior benzoxazine hybrid material containing 10% and 30% titanium dioxide was unobvious. Adhesion force and roll angle of benzoxazine hybrid surface containing 30% titanium dioxide after 210℃ polymerization from increased 0.72 nN to 5.76 nN and 4° to 60° through UV exposure, respectively. This behavior was useful to apply on a micro-liquid transformation system. In our work, we transformed a droplet liquid stably between two plates spincoating benzoxazine containing 30% titanium dioxide after 210℃ polymerization through UV exposure. The micro-liquid transformation is an important property currently for application of biochip.
