FIELD: nanotechnology; electrical engineering.
SUBSTANCE: invention relates to nanotechnology, electrical engineering and electronics and can be used in making conductive fillers for functional composites or components of electronic circuits. Multilayer carbon nanotubes obtained by pyrolysis of hydrocarbons using catalysts are placed in 6 % solution of potassium iodine or iodide in isopropanol and continuously mixed in 0.5–1.0 h. Then mixture is dried and heated in furnace in argon atmosphere at temperature of 600–650 °C for 2 hours.
EFFECT: invention enables to obtain multilayer nanotubes with a modified surface, having high electrical conductivity, simplifying the method of obtaining said nanotubes and using only available reagents.
