| Abstract: | Water-based magnetic fluid of nanoscale Fe3O4 modified by β-cyclodextrin was prepared via a two-step route.The effects of pH value,dosage of modifying agent,and temperature on modification efficiency were investigated.The structure and magnetic performance of the product were analyzed by using a scanning electron microscope,Fourier transformation infrared spectrometer,and a vibrating sample magnetometer.Results indicate that the magnetic fluid has an average grit size of about 50 nm and possesses stable magnetic performance,with saturated magnetic intensity being as much as 1.78 emμ/g.Besides,the temperature of the magnetic liquid can be increased by over 41 ℃ under high-frequency alternating magnetic field,showing potential in treating cancer by magnetic heating. |
