摘要
以氨水为催化剂,通过水解正硅酸乙酯制备了乳白色二氧化硅溶胶,采用静电自组装薄膜技术制备了聚电解质/二氧化硅复合薄膜,并通过热处理制备了二氧化硅薄膜。采用透射电镜、红外光谱仪、721分光光度计对二氧化硅溶胶和薄膜进行了分析。
Translucent SiO2 sols are prepared from TEOS using NH3 · H2O as catalyzer, polyelectrolyte/ SiO2 composite films are fabricated via electrostatic self-assembly multilayer method, and SiO2 thin films are formed by heat-treating the polyelectrolyte/SiO2 composite films to eliminate the polyelectrolyte and other components in compos ite films. The prepared SiO2 sols, polyelectrolyte/SiO2 composite films and SiO2 thin films are investigated with transmission electron microscope, fourier transform infrared spectrophotometer and 721 spectrophotometer.
