摘　　要：采用溶胶-凝胶法和含氟聚合物表面修饰法制备了高疏水性纳米Al2O3薄膜。用异丙醇铝与乙酰丙酮反应制备铝-乙酰丙酮螯合物，由此控制异丙醇铝的水解。并用接触角测量仪、721型分光光度计、原子力显微镜（AFM）等仪器对Al2O3薄膜的结构和表面形貌进行表征。结果表明，该膜具有疏水性强、透明度高的特点。将该薄膜涂覆在潜水艇潜望镜、汽车观后镜以及容易被腐蚀的物体的表面，如太阳能电池板等，具有很好的使用价值。The transparent hydrophobic nano Al2O3 thin film is prepared using sol-gel processing. The hydrophobicity of the film is obtained by surface modifying of FAS. In this experiment, isopropyl alclhol and aluminum acetylacetone act as synthesis-acetylacetone chelate. The structure of the film is determined by contact angle measuring instrument. The transmission performance is determined by 721-spectrophotometer and the surface morphology of the film prepared is characterized by AFM. This film has a characteristic of high hydrophobicity and trasparency. When coated on the submarine periscope, car as well as other things which corrupt easily, such as solar cells, the film has a good value.
