超疏水自潔表面之製程改良研究

Abstract

所謂的超疏水自潔表面在自然界中很常見，其中以蓮花葉表面的超疏水自潔最為有名，亦即著名的「蓮花效應」（Lotus Effect），藉由雨水的沖刷就能輕易帶走表面的汙染物。目前此生物特性在各領域均具有潛在的應用價值，也引起不少廣泛的研究興趣，降低表面清洗的次數、清潔維護的成本，在環保節能上有很大的貢獻。 本研究利用溶膠-凝膠法來製備表面的粗糙程度，並利用控制陽極表面處理所生成的多孔性氧化鋁孔洞大小，來提升奈米粒子的附著性及穩定性。透過穩定性測試找出最佳陽極處理製程。 本研究改良傳統舊有的加熱爐燒結，開發了一快速燒結設備以及一快速降溫設備，並成功整合了兩套設備，完成了完整製程。綜合以上兩部分的改良，在製程的生產效率大幅提升，原本將近一天的製程時間，可縮短至半天以內即可完成，亦不影響其效果。

In nature, super-hydrophobic self-cleaning surface is very common, including the lotus leaf surface which is the most famous, that is “Lotus Effect”. It can easily take the surface contaminants away by raining. Now, people gradually attach great importance to the biological properties’ application due to environmental protection. In this thesis, the hierarchical structure is fabricated with silica nanoparticles by sol-gel method. Producing a homogeneous nano-porous anodic aluminum oxide by anodized to strengthen the hierarchical structure and improve the adhesion and stability of the nanoparticles. To find the best anodized process by stability test. In order to improve the traditional heating furnace, we develop the new fast-sintering equipment and the new fast-cooling equipment. And successfully combine the two sets of equipment to complete the super-hydrophobic self-cleaning process. Based on the above improvement, the process efficiency is increased. And it will not affect the super-hydrophobic property.
