The Study of Influence of Fluorine Ether Acids on Property of Magnetic Fe3O4 Nanoparticles
For prepare magnetic liquids with good property, the authors prepared Magnetic Fe3O4 nanoparticles by co-precipitation and magnetic Fe3O4 nanoparticles were modified by the surfactant. Analyzed the product of Magnetic Fe3O4 nanoparticles by X-ray Diffraction Analysis, Transmission Electron Scanning, Saturation Magnetization Test and the result indicate that Magnetic Fe3O4 nanoparticles modified by the surfactant have good dispersity, but it’s saturation magnetization is lower than Magnetic Fe3O4 nanoparticles which notmodified by the surfactant.
