FIELD: technological processes.
SUBSTANCE: invention can be used in designing components of electronic equipment, sensors, supercapacitors, electromagnetic screens, contrasting materials for magnetic resonance tomography, magnetic information recording systems. Method of producing nanocomposite magnetic and electrically conductive material involves simultaneous dissolving in an organic solvent salts Co (II) and Fe (III) and polymer matrix - polyphenoxazine (PFOA), removal of solvent with formation of precursor and its subsequent infrared heating. Organic solvent used is dimethylformamide (DMF), dimethylsulphoxide (DMSO) or N-methylpyrrolidone. Single dissolution is combined with additional addition of single-wall carbon nanotubes (SWCNT) to the solution. Removal of solvent is carried out at 60–85°C. Infrared heating is carried out in an argon atmosphere at 350–600 °C for 2–10 minutes. Nanocomposite material containing 5–10 wt. % of the polymer of SWCNTs is obtained, on which Co-Fe nanoparticles are fixed with their total content in material of 2–45 wt. %.
EFFECT: invention enables to obtain nanocomposite material, having both electroconductive and superparamagnetic properties, high saturation magnetisation, electrical conductivity and thermal stability.
