Abstract

Spherical hollow two-component antimony doped tin oxide/titanium dioxide (AT@TiO₂) microspheres with uniform size (~280 nm) were prepared by a two-step hydrothermal method. The morphology, crystal structure and microstructure of hollow AT @TiO₂ microspheres were characterized using XRD, SEM, EDS and HRTEM. By adding different contents of hollow AT@ TiO₂ into the organosilicone resin matrix, the composite coating was prepared on glass with an anti-reflective MgF₂ layer. The optical and thermal insulation properties of the composite coatings were studied. The light transmission of AT@TiO₂/Organosilicone resin on MgF₂ coated glass can reach ~80%, when the content of the hollow AT @TiO₂ microspheres was controlled at 1.5 wt.%. Moreover, the coating of AT@ TiO₂/ Organosilicone resin on MgF₂ coated glass can lower the indoor temperature of a self-made incubator by 11.25℃. The prepared AT@TiO₂/Silicone resin coating on MgF₂ coated glass show a great potential in the application of energy saving.

采用两步水热法制备了尺寸均匀（约 280 nm）的球形空心双组分掺锑氧化锡/二氧化钛（AT@TiO2）微球。利用 XRD、SEM、EDS 和 HRTEM 对空心 AT@TiO2 微球的形貌、晶体结构和微观结构进行了表征。在有机硅树脂基体中加入不同含量的空心 AT@TiO2 微球，在玻璃上制备了具有抗反射 MgF2 层的复合涂层。研究了复合涂层的光学和隔热性能。当空心 AT@TiO2 微球的含量控制在 1.5 wt.% 时，AT@TiO2/有机硅树脂在 MgF2 涂层玻璃上的透光率可达约 80%。此外，在 MgF2 镀膜玻璃上涂覆 AT@TiO2/ 有机硅树脂可使自制培养箱的室内温度降低 11.25℃。在 MgF2 镀膜玻璃上制备的 AT@TiO2/ 有机硅树脂涂层在节能方面具有很大的应用潜力。
