Аннотация
This work describes the preparation of an organic-inorganic composite and the study of its characteristics. Particles of core (BaTiO3)–shell (SiO2–CoFe2O4) type were used as inorganic composite. These inorganic particles are used for the preparation of composites based on poly(vinyl alcohol) cyanoethyl ether synthesized in an external direct magnetic field. It is determined that the dielectric permittivity of the composites formed in an external magnetic field at the optimal content of the magnetic phase (concentration of CoFe2O4 = 20.3%) is four times as large (ε = 460 at the frequency f = 1000 Hz) as that of analogous composites formed without a magnetic field.
