Abstract:	本研究目標為開發具有易潔且耐磨表面的透明玻璃塗層。生活中有許多玻璃產品如手機面板、櫥窗玻璃等，都望能具有自潔或易潔的疏水撥油表面，又能耐長時間使用而無擦傷和磨損等問題。疏水撥油且耐磨之表面通常是由接枝長鏈氟烷來達成。以業界常用之標準來說，要能在一公斤負載下承受一萬次鋼絲絨磨擦循環而仍然保持疏水撥油性。由於長氟碳鏈可能導致的健康和環境問題，多氟烷在歐盟國家已被禁用。Masheder等人最近開發出了一種無氟而具有優異疏水撥油性能的鋯與長烷羧酸混合塗層。不幸的是該塗層並不耐用。我們認為先鍍膜後再進行表面接枝，應該可以改善其耐用性。而除了接枝長烷鏈外，或許改用聚矽氧烷鏈也可能達到疏水撥油的易潔效果。至於耐用程度提高的關鍵，應該在於表面接枝之撥水劑與鍍膜的鍵結強度。上述長(矽氧)烷鏈撥水劑通常藉由酸基、胺基或矽醇尾端與玻璃表面水解產生之羥基鍵結，但是此類鍵結之接著力不夠強且易於水解脫落。而磷酸基與氧化鋯或氧化鈦表面鍵結是所知接枝中最強的。是故將從此二方向尋找氟烷鏈的替代方案。 ;We have developed a transparent, easy cleaning and durable hydrophobic coating for the glass surface. Such surface is very desirable for touch screens that have become an essential part of our daily life. For practical applications, the coatings should also be strongly adhered to the substrate and should resist at least a few thousand cycles of steel-wool scratching without losing its hydrophobicity. Previous easy-cleaning surface relies on the hydrophobic behavior of poly-fluorocarbon coupling agents, which will be banned in European Union nations soon. Masheder et al. have recently developed a fluorine-free zirconiumcarboxylic hybrid coating that exhibits excellent dynamic oleophobicity and anti-fingerprint property. Unfortunately, the durability of this coating is far inferior to that of the current commercial products.
