摘要
用溶胶凝胶法制备二氧化钛胶体,发现十二烷基硫酸钠(SDS)和聚乙二醇(PEG)两种表面活性剂可以改变纳米二氧化钛的最终形貌。用X射线、SEM表征分析了两种表面活性剂对TO2晶型、粒径、形貌的影响。
To improve conglobation by sol-gel method with different surfactant. Nano- TiO2 colloid is prepared by Sol-gel method and crystal structure, particle size and morphology are characteriz, cd by X- ray or SEM. Results show that： different surfactants produce different morphology. Moreover, surface area is enlarged and conglobation is inhibited.
