摘要

本實驗先以溶膠凝膠法製造出二氧化矽奈米球，目的在於替底表面能薄膜提供粗糙度，接著採用有機無機混成的方式用低表面能材料對二氧化矽奈米球表面作改質。之後利用旋轉覆膜技術將雙疏薄膜附著在玻璃基板上。實驗分析部份，用SEM觀察薄膜顯微結構；紫外光─可見光分光儀測量薄膜在可見光波長之透光度；薄膜水接觸角與油接觸角的量測。實驗結果顯示出薄膜的透光度受低表面能材料的濃度與熱處理溫度影響；接觸角分析顯示低表面能薄膜搭配適合的粗糙度，可以將薄膜的雙疏性質進一步提升。

We synthesize silicon dioxide nano-spheres by sol-gel method. Then we use surface modification for nano-spheres by low-surface energy materials via organic–inorganic hybrid method. After that time, we spread modified nano-spheres on glass substrate via spin coating technologies. The morphology of the thin films was analyzed by Field - Emission Scanning Electron Microscope, UV/Visible Spectrophotometer, and Contact Angle Meter.Experimental results show that transparent ratio in the range of visible light of the thin films was influenced by concentration of low-surface energy materials and heat treatment tempture; the contact angles of the water/oil drops show the thin films characteristic of amphiphobic would enhance when the thin films obtain proper roughness.
