| Abstract: | Silylanization magnetic microspheres with surface amido groups were prepared by solution polymerization.Obtained samples were characterized by Transmission electron microscope and Fourier transform infrared spectrometer.Results indicate that particle size of the samples is well-distributed and is above 15nm.Magnetic microspheres possess core-shell structure with the core of magnetic substance and the shell of 3-amino propyl triethoxysilane.Research results on suspension stability indicated that magnetic microspheres possess good uspension stability and strong magnetic responsiveness. |
