Description
Summary:This paper demonstrated our discovery of the movement effect of BiFeO3 nanoparticles in solution by strong electrical polarization.First,BiFeO3 nanoparticles were prepared by ball milling and characterized by SEM.Then,the preparation of BiFeO3 solution was finished.BiFeO3 nanoparticles are found to move in solution due to electrical field.The movement velocity ofBiFeO3 nanoparticles,which is about 10 μm·s-1,is influenced and controlled by the applied electrical field.The concentration of BiFeO3 solution and the nanoparticle sizes also have effects on its movement properties.The movement of BiFeO3 nanoparticles in solution is induced by strong polarization,and BiFeO3 nanoparticles have net negative electric charges because of the electrostatic force between BiFeO3 nanoparticles and the negative ions in water resolver.
