The use of carbon nanotubes to create materials that absorb electromagnetic radiation and electrodes of supercapacitors

Carbon nanotubes are effective nanomodifiers - providing the formation of a variety of thermal and electrophysical properties in composite materials. The functional purpose of composite materials determines the type and concentration of carbon nanostructures. The use of carbon nanostructures in polymer composites intended for electromagnetic shielding and electrode materials of supercapacitors is a promising direction in modern materials science. The method of manufacturing a radio-absorbing composite material included impregnation of a polyurethane foam billet - an aqueous composite suspension consisting of water, an acrylic copolymer, and carbon nanotubes "Taunit-MD". Structural studies of carbon nanotube samples were performed using transmission and scanning electron microscopy. To do this, PAM and SAM studies were performed using a HitachiH-800 electron microscope with an accelerating voltage of up to 200 Kev. For research purposes, electrodes with an area of 2 cm2 were made from carbon materials...
