摘要

This paper deals with the investigation of the kinetics of nanocomposite polarization based on polymeric matrix: 1) collagen; 2) polystyrole; and 3) magnetite nanoparticles in perpendicular electric and magnetic fields. It is shown that magnetic field influences the buildup of nanoparticle polarization plane into the electric field. The influence of magnetic field on the dielectric permittivity of nanocomposites has been determined. It is shown that by changing the magnetic field within , the value of nanocomposite dielectric permittivity decreases and at , it has a minimum value, but beginning with , it increases. It is shown that magnetic field also influences the depolarization of magnetite nanoparticles. While changing the direction of the magnetic field, one can accelerate or retard the depolarization of magnetite nanoparticles.
