摘　　要：疏水性对户外显示设备具有重要作用。本文探讨了全氟硅烷改性二氧化硅薄膜在玻璃基底上的性能,并研究了正硅酸乙酯浓度对该薄膜疏水性和透过率的影响。结果表明:该浓度为15%制备十七氟癸基三乙氧基硅烷改性薄膜,可实现154.1°超疏水性能和(400~800)nm波长超过98%的平均透过率,具有可行性。Hydrophobicity plays an important role in outdoor display equipment.The properties of perfluorosilane-modified silica films on glass substrates were investigated,and the effects of the concentration of ethyl orthosilicate on the hydrophobicity and transmittance of the films were studied.The results show that the preparation of HFC-decyl triethoxysilane modified films with a concentration of 15%can achieve superhydrophobic properties of 154.1°and average transmittance of more than 98%at(400~800)nm wavelength,which is feasible.
