摘要(中)

油汙染的影響使得油水分離技術受到重視，而此技術可以應用在薄膜製程。常見於油水分離的薄膜製程有靜電紡絲法、電漿表面處理、模板合成法、自組裝法及溶膠凝膠法。而溶膠-凝膠法有著製程簡便、低成本、低汙染、高穩定性的優勢。因此本研究以溶膠-凝膠法的方式製作出奈米尺度的SiO2顆粒，並藉由表面改質對其進行化學特性的變化，進一步的應用在油水分離的實驗上。
製備出M-SiO2-OH-SSM後，為了證明其表面的物理與化學特性，除了對不同時間點的不鏽鋼網(SSM)進行FTIR、SEM、WCA的量測，分析其表面結構、粒徑大小及水接觸角的變化。接著在對製程溫度與時間參數的進行調控，可以製作出擁有最高WCA，並且在多項耐久性測試上都有著維持穩定且高效的分離效率。最後進行更深入的乳化液測試，在一定的濃度下，可以穩定且完整的乳化液分離。
本研究成功的以實驗室自行合成的SiO2奈米球為材料，改質後製備在SSM上，得到的M-SiO2-OH-SSM具有超疏水特性、高效且穩定的分離效率、極佳的機械性質，並且可以用在乳化液分離上。

摘要(英)

The influence of oil pollution makes oil-water separation technology pay attention, and this technology can be applied in the thin film process. Common thin film processes used in oil-water separation include electrospinning method, plasma treatment, templates method, self-assembly method and Sol-Gel method. The sol-gel method has the advantages of simple process, low cost, low pollution, and high stability. Therefore, in this study, nanometer-scale SiO2 particles were produced by the sol-gel method, and the chemical properties were changed by surface modification, which was further applied to the experiment of oil-water separation.
After preparing M-SiO2-OH-SSM, in order to prove the physical and chemical characteristics of the surface. Measuring FTIR, SEM and WCA of the stainless steel mesh (SSM) at different time points. Furthermore, analyze the change of surface structure and particle size water contact angle. Then, by adjusting the temperature and time parameters of the process, we can produce the highest WCA which can maintain stable and efficient separation efficiency in many durability tests. Finally, a more in-depth emulsion test is carried out. Under a certain concentration, stable and complete emulsion separation can be achieved.
In this study, SiO2 nanoparticle synthesized in the laboratory were used as materials, and they were prepared on SSM after modification. The product M-SiO2-OH-SSM has super-hydrophobic characteristics, high efficiency and stable separation efficiency, and excellent mechanical properties which can be used in emulsion separation.
