超臨界為一種特殊的相態,透過溫度與壓力的控制,可使物質的性質介於液態與氣態之間,具有優於液體的傳輸性、滲透性,與具備氣體所沒有的溶解力等特點。本論文嘗試開發一種將超臨界二氧化碳的優點運用於噴塗之新製程,透過超臨界二氧化碳與TEOS溶液混合所形成之膠體溶液在玻璃表面來執行塗佈與噴塗,其鍍層得到均勻的TEOS膠體顆粒分散於鍍層中,增加表面粗糙度與疏水性等。在本研究中探討該製程在不同陳化時間、乙醇濃度等參數下的成效,而進一步嘗試改變參數再觀察其成效時,利用田口式品質設計方法來減少不必要的實驗成本找出最佳參數,並發現塗佈後之鍍層接觸角與膠體溶液之陳化時間、乙醇濃度有較大的相關。本論文將針對以上的研究進行分析並探討其成因。發現在不添加任何添加劑的形況下,單純以TEOS溶液縮合交聯產生之二氧化矽來達成疏水性的效果可達120°之接觸角。

As a special state, the supercritical phase of any substance can have superior transmissibility and permeability than its liquid phase, and better solubility than its gas phase. In this study, an attempt to improve the morphology and hydrophobic property by mixing supercritical carbon dioxide with TEOS solution in the spreading and spraying processes for gel coatingon the glass surface was performed. Among all the parameters, such as aging time and alcohol concentration, et al., which influence the surface characteristics of the dried silica coating, a Taguchi method with L16 orthogonal table was employed to study their effects. It was found the contact angle of the specimen surface was mostly influenced by the alcohol concentration in the TEOS solution and the aging time. It was also found that without any extra additive the hydrophobic silica coating surface prepared from the condensation reaction of TEOS could reach a contact angle of 120o.
