摘要
根据户外照明系统自清洁功能的需求, 基于光学薄膜理论, 对复合膜折射率和质量配比进行了理论分析与模拟, 采用电子束共蒸发技术镀制TiO2/Al2O3复合膜, 并对其做真空退火处理.在单晶控系统中, 通过控制左右两电子枪的束流, 镀制了不同质量配比复合膜.亲水性测试和甲基橙实验表明, 复合膜中TiO2的质量配比越高, 自清洁效果越好, 但亲水性和可见光透过率会降低.对不同质量配比的复合膜进行了检测和分析, 并通过调整质量配比来优化试验方案, 结果表明, TiO2/Al2O3质量配比为9: 1时, 该薄膜既具有自清洁亲水作用, 又具较高的可见光透过率.
Abstract
According to the environmental requirements of self-cleaning quality for outdoor lighting system, the refractive index of composite film and the quality ratios were analyzed and simulated based on the theory of optical thin film. The method of electron beam evaporation was used to plate the Ti02/A1203 composite film, and then the composite film was given for the vacuum annealing treatment. By controlling the beams of the left and right of the electron gun, the different mass ratios plating composite film was prepared in the single-crystal control system. The hydrophilic test and the Methyl orange experiment shows that, the higher the quality ratio of Ti02 is, the better the self-cleaning effect is, but the ability of hydrophilic and visible light transmittance are both reduced. The composite film with different quality ratios were tested and analyzed. And the paper adjusts the mass ratio to optimize the test plan, the results show that, when the mass ratio of the Ti02/A1203 is 9∶1, the film not only has a self-cleaning hydrophilic interaction, but also with a high visible light transmittance.
