摘要
为了探究纳米粒子的紫外屏蔽性能,以TiOSO_4、ZnCl_2为原料,以NH_3·H_2O为调节剂,以PEG 400为分散剂,采用超声沉淀法,在不同煅烧温度、煅烧时间条件下制备了纳米TiO_2、ZnO以及TiO_2/ZnO材料;采用FT-IR、XRD、XPS、UV等方法对纳米粒子进行了表征,考察纳米粒子的紫外屏蔽性能.表征结果显示:当纳米TiO_2粒子在800℃下煅烧4 h、纳米ZnO粒子在500℃下煅烧4 h时,其紫外屏蔽性能最佳;TiO_2/ZnO复合粉体相对于单一纳米TiO_2、ZnO粒子屏蔽紫外线的能力更强.
In order to investigate the UV-shielding property of nanoparticles, TiO2, ZnO and TiOz/ZnO were prepared by ultrasonic precipitation at different calcination temperature for different calcination time using titanyl sulfate, zinc chloride as raw material, ammonia as conditioning agent and PEG 400 as dispersant. The nanoparticles were characterized by FT - IR, XRD, XPS, UV, and the UV -shielding properties of the nanoparticles were investigated. The results show that the UV-shielding property is best when the TiO2 nanoparticles are calcined at 800 益 for 4 h and the ZnO nanoparticles are calcined at 500 ℃ for 4 h. However, the TiOz/ZnO composite nanoparticles have stronger UV-shielding property than single TiO2 and ZnO nanoparticles.
