L.M. Litvinenko of the National Academy of Sciences of Ukraine popup.description2 The aim of the 1st stage of the project is to test the method of investigations of the efficiency of electromagnetic radiation shielding of thin films; the study of the kinetic regularities of the formation of Ni-Fe and Ni-Co nanosystems in order to optimize the methods of obtaining bimetallic nanopowders. As a result of the conducted investigations on the first stage of the project: 1) a device based on the vector network analyzer NanoVNA was developed to study the effectiveness of EMF shielding of thin (up to 500 μm) films in the wave frequency range of 50 kHz - 900 mHz; 2) the influence of the initial concentrations of precursors (Ni2+, Fe2+, Co2 ions) on the kinetics of formation of Ni-Fe and Ni-Co bimetallic nanoparticles in alkaline solutions of ethylene glycol was studied; 3) the effect of temperature on the kinetics of formation of Ni(x)Fe(100-x) and Ni(x)Co(100-x) bimetallic nanosystems has been studied; 4) the effectiveness of electromagnetic radiation shielding by a film composite based on the MMA/BMA copolymer and nickel-containing nanoparticles was investigated.
