用乙酰乙酸乙酯对Al（O-sec-C4 H9）（3）进行化学修饰，在聚对苯二甲酸乙二酯（PET）基底上制备了Al 2 O3凝胶膜。发现在室温下干燥然后浸入60 ℃热水中的Al 2 O3凝胶膜上形成约20-50 nm的小粗糙度。当水解的氟烷基三甲氧基硅烷涂覆在Al 2 O3膜上时，获得了对水的接触角大于150 °的透明薄膜。
Al2O3 gel films were prepared on poly(ethylene terephthalate) substrates from Al(O-sec-C4H9)(3) chemically modified with ethyl acetoacetate. A small roughness of about 20-50 nm was found to form on the Al2O3 gel films dried at room temperature and then immersed in hot water at 60 degrees C. When hydrolyzed fluoroalkyltrimethoxysilane was coated on the Al2O3 films, transparent thin films with contact angle for water to be more than 150 degrees were obtained.
