本研究以旋轉塗佈法(spin coating)，觀察在不同轉速條件下製備之聚苯乙烯奈米球(polystyrene nanospheres)形貌，並製備出單層聚苯乙烯奈米球薄膜，接著，分析單層奈米球薄膜在不同氧電漿蝕刻(oxygen plasma etching)時間下的粒徑大小與分佈情形，再利用電漿增強化學氣相沉積系統(PECVD)，以四甲基矽烷(tetramethylsilane)為源材料，在結構化奈米球表面沉積有機矽基(organosilicon)疏水薄膜，並以稀釋氫氟酸溶液改質有機矽基疏水薄膜的表面特性，提升提升薄膜的疏油效果。研究中，透過原子力顯微鏡 (AFM)、場發射掃描式電子顯微鏡(FE-SEM)、紫外光-可見光光譜儀(UV-VIS)，分別觀察結構化奈米球以及有機矽基疏水薄膜改質前後的表面粗糙度、表面/橫截面形貌與光學穿透率，以傅立葉轉換紅外線光譜儀(FTIR)以及X光光電子能譜儀(XPS)分析薄膜化學組成與鍵結型態，並利用接觸角量測系統，量測表面改質前後有機矽基薄膜的表面疏水/疏油特性。研究結果顯示，利用氧電漿蝕刻製程能夠有效控制奈米球粒徑大小及分佈，大幅提升後續沉積有機矽基薄膜的表面粗糙度，有機矽基薄膜沉積在經過適當氧電漿蝕刻之奈米球表面，水滴接觸角可大幅提升，此外，研究結果亦顯示，有機矽基薄膜表面經UV-Ozne照射處理後，再以稀釋氫氟酸溶液氟化蝕刻形成矽-氟鍵結，有助於顯著改善薄膜表面的疏油特性。

In this study, the spin coating method was used to observe the morphology of polystyrene nanospheres prepared under different rotation speeds to prepare a single-layer polystyrene nanosphere film, and then analyze the single-layer nanospheres. The particle size and distribution of the rice ball film under different oxygen plasma etching time, and then use the plasma enhanced chemical vapor deposition system (PECVD), using tetramethylsilane as the source material, An organosilicon hydrophobic film is deposited on the surface of the structured nanosphere, and the surface characteristics of the organosilicon hydrophobic film are modified with a hydrofluoric acid solution to enhance the oleophobic effect of the film. In the research, through the atomic force microscope (AFM), field emission scanning electron microscope (FE-SEM), ultraviolet-visible light spectrometer (UV-VIS), the structured nanospheres and the organic silicon-based hydrophobic film were observed before and after modification. Roughness, surface/cross-section morphology and optical transmittance, Fourier transform infrared spectrometer (FTIR) and X-ray photoelectron spectrometer (XPS) were used to analyze the chemical composition and bonding state of the film, and the contact angle measurement system was used , Measure the hydrophobic/oleophobic properties of the organosilicon-based film before and after the surface modification. The research results show that the use of oxygen plasma etching process can effectively control the size and distribution of nanospheres, and greatly improve the surface roughness of subsequent deposited organosilicon-based films. The organosilicon-based thin films are deposited on nanoparticles that have been properly etched by oxygen plasma. The contact angle of water droplets on the surface of the ball can be greatly increased to more than 120˚. In addition, the research results also show that the surface of the organosilicon-based film is treated with UV-Ozne and then fluorinated and etched with a hydrofluoric acid solution to form a carbon-fluorine bond. Helps greatly increase the contact angle of oil droplets on the surface of the film.
