| titleOfInvention | Hybrid magnetic and electroconductive material based on polymer, bimetallic nanoparticles and carbon nanotubes, and method for production thereof |
| abstract | FIELD: electrical equipment. n SUBSTANCE: invention can be used in electronic engineering for production of electrochemical current sources, sensors, supercapacitors and magnetic information recording systems, in medicine for making electromagnetic screens, contrasting materials for magnetic resonance tomography, when purifying water in combination with magnetic separation, as well as in making antistatic coatings and materials which absorb electromagnetic radiation in different wavelength ranges. Hybrid nanocomposite magnetic and electroconductive material includes a polymer matrix - polydiphenylamine (PDPA), single-walled carbon nanotubes (SWCNT), on which bimetallic Co-Fe particles are fixed in form of a solid solution, with size of 450–1600 nm. Total content of Co-Fe particles in material 2–45 wt. %, and SWCNT - 1–10 % of polymer weight. To obtain said material, a precursor is first obtained by dissolving PDFA, SWCNT and Fe (III) salts and Co (II) salts in an organic solvent with subsequent removal of solvent at 60–85 °C. Then performing precursor heating in argon atmosphere at 400–600 °C for 2–10 minutes. Cobalt salt Co (II) used is Co(OOCCH 3 ) 2 ⋅4H 2 O, Co(CH 3 COCH=C(CH 3 )O) 2 , CoCO 3 ⋅6H 2 O or Co(NO 3 ) 2 ⋅6H 2 O with content of cobalt 1–15 % of weight of polymer matrix. Fe (III) iron salt used is FeCl 3 ⋅6H 2 O, Fe(NO 3 ) 3 ⋅6H 2 O or Fe(CH 3 COCH=C(CH 3 )O) 3 at iron content of 2–30 % of weight of polymer matrix. Organic solvent used is dimethylformamide (DMF), dimethylsulphoxide (DMSO) or N-methylpyrrolidone. n EFFECT: hybrid nanocomposite material having both electroconductive and superparamagnetic properties, heat resistance (thermal stability) and saturation magnetization, is obtained using a simple method. n 5 cl, 1 tbl, 24 ex, 23 dwg |
