FIELD: nanotechnologies.
SUBSTANCE: first, a suspension is prepared containing as a liquid dispersion medium an ethylene glycol and a carbon nanomaterial, for example graphene, graphene oxide, reduced graphene oxide, single-walled carbon nanotubes, two-layer carbon nanotubes, multilayer carbon nanotubes or mixtures thereof, and it is treated with ultrasound. Then suspension is heated to 95 °C. To the heated suspension adding dropwise an organic solvent with a boiling point below ethylene glycol, for example ethanol, isopropanol, acetone. Droplet falling height is 1–15 mm, the organic solvent to the suspension volumetric ratio is from 1/2 to 7/1. Formed on the liquid dispersion medium surface thin film of a carbon nanomaterial is separated, transferred to a substrate, and dried.
EFFECT: invention allows to obtain homogeneous and dense thin films based on carbon nanomaterials and to increase their surface resistance.
