Description
Full text : The polymer magnetic microspheres (PMMS) have been prepared on the basis of collagen and polystyrene by introduction of magnetic nanoparticles. The curve of magnetization of PMMS is very close to the theoretical one, calculated on the basis of Langeven equation. Magnetic properties of PMMS remain unaltered for a long time (two years and more), that can be indicative for a rigid fixation of nanoparticles in polymer matrix and for stability of their concentration. With application of transmission electron microscopy it has been shown, that nanoparticles are separated from each other and are not capable to aggregate. Magnetizing of PMMS arises according to Neel mechanism. Orientation of magnetic moments of nanoparticles in the externally applied magnetic field occurs by its rotation inside nanoparticles
