FIELD: nanotechnology.
SUBSTANCE: method of obtaining carbon nanocrystalline material includes preparing a solution of polyacrylonitrile (PAN) (Mη=1×105) in dimethyl formamide (DMF) with c CPAN=1÷5 wt %, keeping the PAN dissolution in DMF for a period of 72 hours at 25°C, application on a glass-carbon base a layer of the PAN/DMF solution, drying the polymeric layer in a drying cabinet at 90°C for a period of 0.5÷1 hour, heat the film at a speed 2÷20°C/min under the influence of IR-radiation and keeping the film for more than 1 second at 800÷900°C, P=10-3 mm hg.
EFFECT: invention makes it possible to obtain carbon nanocrystalline material, sensitive to pH environment.
