FIELD: chemistry.
SUBSTANCE: metal-polymer nanocomposite magnetic material includes a polymer matrix and nanoparticles Fe3O4 dispersed therein. As a polymer matrix, a matrix of poly-3-amino-7-methylamino-2-methylphenazine PAMMP is used with the content of the nanoparticles Fe3O4 in the material 1-70 wt % of PAMMP. To produce a metal-polymeric nanocomposite magnetic material by oxidative polymerization of a monomer in situ on the surface of the nanoparticles Fe3O4 in the presence of an aqueous oxidant solution, 3-amino-7-dimethylamino-2-methylphenazine hydrochloride-neutral red is used as a monomer, and ammonium persulfate is used as an oxidant. The molar ratio of the oxidant to the monomer in carrying out the oxidative polymerization is 2-5. Prior to oxidative polymerization, the monomer is dissolved in an organic solvent, which is acetonitrile, dimethylformamide or dimethylsulfoxide, to a concentration of 0.01-0.05 mol/l. Nanoparticles Fe3O4 are added to the solution in the amount of 1-70 wt % of PAMMP. Oxidative polymerization is carried out at 0-60°C for 1-6 hours.
EFFECT: invention allows to increase the saturation magnetization of a hybrid metal-polymer nanocomposite magnetic material with super-magnetic properties, high thermal stability, to simplify its production, and to reduce energy costs.
