摘要

采用溶胶-凝胶浸涂技术在玻璃基体上制备了TiO2-ZrO2复合涂层，以水性氧硫酸钛（TOS）和正丙氧基锆（ZP）为前驱体，分别在500℃/1h下煅烧。通过FTIR、拉曼光谱、紫外可见光/NIR、GIXRD、FESEM、TEM和XPS对样品进行了表征。涂层的厚度和RI是用椭圆测量法测量的。涂层厚度为110±10nm，折射率为1.95±0.05的镀膜玻璃具有良好的硬度（≥3H）和附着力。通过FTIR和XPS分析证实了Ti-O和Zr-O的结合性质，而拉曼和GIXRD研究揭示了TiO2-ZrO2复合材料的结晶性质。FESEM和TEM图像分别揭示了沉积涂层的无裂纹和蜘蛛网状性质。涂层的TiO2-ZrO2复合材料在350-2500nm的波长范围内显示出>20%的平均反射。上述基于纳米复合材料的镀膜玻璃可以用作高效节能建筑构件的热反射窗。图形摘要

A Preparative Approach of TiO2-ZrO2 Coating Using Aquo-Based TiO2 Precursor Useful for Light Reflective Application

TiO2-ZrO2 composite coating was prepared onto glass substrate via sol-gel dip-coating technique using aquo-based titanium(IV) oxysulphate (TOS) and zirconium(IV) n-propoxide (ZP) as the precursor sources of TiO2 and ZrO2, respectively followed by calcination at 500oC/1 h. The samples were characterized by FTIR, Raman, UV/visible/ NIR, GIXRD, FESEM, TEM and XPS studies. The thickness and RI of the coating were measured ellipsometrically. The coated glasses with coating thicknesses of 110±10 nm having refractive index of 1.95±0.05 were found to be uniform with good hardness (≥3H) and adhesion properties. The bonding nature of Ti-O and Zr-O was confirmed by FTIR and XPS analyses while Raman and GIXRD studies revealed the crystalline nature of TiO2-ZrO2 composite. FESEM and TEM images revealed crack-free and spider web-like nature of the deposited coating, respectively. The coated TiO2-ZrO2 composite showed >20% of average reflection within wavelength range of 350-2500 nm. The above nanocomposite based coated glass could be used as heat reflecting window for efficient energy saving building components. GRAPHICAL ABSTRACT
