摘要:

以本征机械性能良好的溶胶-凝胶酸催化SiO2和TiO2薄膜为基础, 设计并制备了具有高透过率和良好机械性能的λ/4/4 SiO2/SiO2-TiO2双层增透膜. 所得薄膜在中心波长处的峰值透过率达到99.9%, 与设计膜层的透过率曲线高度吻合. 经耐摩擦和黏附性测试后, 该双层增透膜峰值透过率基本保持不变, 硬度高达4H, 表明其具有良好的机械性能. 水表面接触角测试结果显示该双层增透膜具有超亲水性, 表现出良好的冷/热防雾效果.

Abstract:

SiO2/SiO2-TiO2 double-layer antireflective(AR) coating with high transmittance and excellent mechanical property was designed and prepared by sol-gel method based on the intrinsically robust sol-gel acid-catalyzed SiO2 and TiO2 thin films. It was found that the maximum transmittance of the obtained double-layer antireflective coating reached 99.9%, well in accordance with the simulated one. After abrasion and hardness test, the transmittance spectra all changed little compared with the original one; and this double-layer AR coating could withstand the 4H pencil hardness test, showing an excellent mechanical property. Moreover, this double-layer coating was superhydrophilic, hence the coating possessed excellent anti-fogging property. The high transmittance, excellent mechanical and anti-fogging property make this double-layer Si O 2 / Si O 2 - Ti O 2 AR coating an alternative candidate in the field of solar cells.

Key words: Thin film design, Double-layer antireflective coating, Mechanical property, Superhydrophilicity, Anti-fogging property
