Abstract

Waxberry-like core-shell SiO@TiO nanoparticles were prepared by liquid-phase deposition (LPD) method. The dip-coating self-assembly of waxberry-like core-shell SiO@TiO nanoparticles has been used to fabricate coatings with excellent antiglare properties in the large angle and wide wavelength range. The field emission scanning electron microscopy (SEM) and transmission electron microscopy (TEM) measurements showed that the surface of SiO nanoparticles were coated by titania as a shell with controllable and uniform thickness. The ultraviolet visible near-infrared spectrophotometer (UV-Vis-NIR) results indicate that the maximum transmittance of the antiglare coating is up to 95.80% in the visible band, whereas that of the pure glass substrate is only 92.10%. The scattering and haze of the films have been measured to show that such specifically structured coatings exhibited good antiglare properties in the large angle and wide wavelength range.

摘要

采用液相沉积（LPD）法制备了杨梅状核壳结构的SiO@TiO纳米粒子。杨梅状核壳结构的SiO@TiO纳米粒子浸涂自组装法被用于在大角度和宽波长范围内制备具有优异防眩光性能的涂层。场发射扫描电子显微镜（SEM）和透射电子显微镜（TEM）测量结果表明，SiO纳米粒子表面被二氧化钛包覆成壳，壳层厚度可控且均匀。紫外可见近红外分光光度计（UV-Vis-NIR）结果表明，防眩光涂层在可见光波段的最大透过率高达95.80%，而纯玻璃基板的最大透过率仅为92.10%。对薄膜的散射和雾度进行了测量，结果表明这种特殊结构的涂层在大角度和宽波长范围内表现出良好的防眩光性能。
