摘要
采用溶胶-凝胶法制备了硬脂酸表面修饰的TiO2纳米微粒,且制得的纳米粒子能够有效地阻止粒子的长大和相互间的团聚,可稳定地分散在多种有机溶剂中,并利用红外谱图(FT-IR)、扫描量热(DSC)、热重分析(TGA)、透射电子显微镜(TEM)、X-衍射(XRD)等手段对粒子进行了表征和研究。
Nano-TiO2 modified by stearic acid was prepared by sol-gel method. The results show that modified TiO2 can be controlled effectively in size and dispersed in most organic dissolvent steadily. All of the above samples were characterized and researched by FT-IR, DSC, TGA, TEM, XRD.
