摘要
以(C2H5)4SiO4、SnCl4·5H2O为原料,采用分步水解法制备以SnO2为芯材、SiO2为壳材的复合型SnO2-SiO2纳米颗粒,以扫描电镜(SEM)观察纳米材料的形貌,并用红外光谱(IR)、X射线光电子能谱(XPS)表征了SnO2-SiO2纳米颗粒的结构,研究不同核壳物质的量比的SnO2-SiO2纳米颗粒对明胶膜的抗静电性能的影响。结果表明:掺加SnO2-SiO2纳米颗粒的明胶膜具有良好的抗静电能力,随着复合颗粒加入量的增加,表面电导和明胶膜的光学密度都随之增加。
The nano-meter SnO2-SiO2 core-shell particles were synthe- sized by hydrolysis method, using （C2H5）4 SiO4 and SnCl4·5H2O as raw materials. The surface texture of nano-meter SnO2-SiO2 particles was observed by SEM, and its structure was characterizated with IR and XPS. The influence of different molar rate of SnO2 and SiO2 on electric conduction rate of the film was studied. The results indicated that the gelatin film mixed by the SnO2-SiO2 nano-meter core-shell particles had good anti-static property. The electric conduction rate and optical density of the film both increased along with the mass fraction of the core-shell nano-particles.
