摘要
分别采用油酸和硬脂酸、油酸、十二烷基硫酸钠和KH-570对纳米Fe3O4进行改性,通过红外光谱、热分析法对改性后粒子进行了表征和研究。结果表明:油酸和硬脂酸的混合酸对纳米Fe3O4的改性效果明显优于其他改性剂。
The Fe3O4 nanoparticles was modified by octadecanoic acid and oleic acid, oleic acid, lauryl sodium sulfa and KH-570. The surface structure and characteristics of modified Fe3O4 nanoparticles were studied and characterized by various experiments and methods such as FT-IR, TGA et al. The results indicated that the Fe3O4 nanoparticles surface was modified notably by oleic acid and octadecanoic acid in comparison with others.
