Influence of conditions and mode of formation of a sublayer based on ethyl cellulose and sulfuric acid on the structure of carbon coatings

The influence of the method for forming the ethyl cellulose layer, the architecture of the two-layer systems based on ethyl cellulose and sulfuric acid on the morphology and phase composition of the carbon coatings formed on their surface is determined. It is established that in the case of laser deposition of ethyl cellulose, the carbon layers deposited on the H$_2$SO$_4$ / EC surface are characterized by a higher Csp$_3$ / Csp$_2$ ratio, compared to the coatings formed on the EC / H$_2$SO$_4$ surface. At the same time, in the case of electron beam deposition of ethyl cellulose, the opposite effect is observed: in the carbon layer deposited on the H$_2$SO$_4$ / EC surface, a lower Csp$_3$ / Csp$_2$ ratio is recorded, compared to the layers on the EC / H$_2$SO$_4$ surface, which is due to the presence of a droplet phase during laser dispersion of ethyl cellulose and, as a consequence, various processes of EC layer structure formation and its catalytic effect on the carbon coating.
