Annotation Presents the results of experimental investigation of surface activity of carbon nanostructures: sensor films on the basis of amorphous nanodispersed carbon, carbon nanofibers and disrupted nanographite. The increase in the electrical resistance of such material at a concentration of vapors of acetone in air is 12000 ppm at room temperature in the order of 4 %. It is shown that the growth of the resistance associated with the change in the concentration of conduction electrons in the contacts between the structural elements of the films.
