 技術摘要： |
A method for making transparent continuous zeolite film is provided. First a transparent precursor sol is prepared, and the precursor sol is processed to a specific concentration. The precursor solution is coated on a surface of a substrate which is heated under an ambiance of 120.about.250.degree. C. in temperature and a humidity less than saturated humidity. The packing of zeolite nanocrystals in the film converted from coated precursor sol has preferred orientation and the film shows super-hydrophobic property. 一種透明沸石膜的製作方法係先加熱包含矽源、金屬原子、水及沸石結構導引分子之混合溶液，以配製出濃縮的可產生沸石之溶液，其中加熱溫度低於攝氏100度，且加熱程序係在形成懸浮沸石前停止，再稀釋可產生沸石之溶液。之後，將可產生沸石之溶液塗佈在基材上，再在攝氏120到250度之溫度下以低於飽和溼度進行處理，以使塗佈於基材上的可產生沸石之溶液轉化為一沸石結晶膜，其中相對溼度係控制在30%到98%間。所獲得之沸石結晶膜有一定排列次序或有疏水性，且因為所形成沸石膜中之沸石結晶及結晶間孔隙皆為奈米尺度故呈現透明。
