Abstract

The paper presents the results on the synthesis of graphene films in premixed hydrocarbon flames. The parameters of combustion, catalytic substrate type selected and the vertical orientation of the flame, providing education of the smallest number of layers with the greatest structural regularity. Found that in a hydrocarbon flame on a nickel substrate is formed mainly 5-10 graphene layers. It is shown that when the angle of inclination of the substrate relative to the vertical axis of the flame from 0° to 30° can obtain the minimum number of layers - 2-3 layers. The research on the effect of the ratio C/O and argon flow on the formation of layered graphene films. The formation of graphene layers are investigated in a wide range of values of C/O = 0.75 to 1.05. It is shown that with increasing values of C/O and the amount of argon in the mixture, forming layers of graphene disorder increases.
