Control of graphene adhesion to substrate during transfer through liquid

The work is dedicated to analyzing the influence of substrate texture and its wettability on the deformation of the graphene layer during transfer through a liquid medium, as well as investigating the transparency effect of graphene wetting on various substrates. The research was conducted on smooth silicon substrates with varying oxide layer thickness and on textured substrates. Experimental evidence demonstrates that the transparency of graphene in terms of wetting changes with variations in the graphene-substrate contact density. Assessments were made regarding the forces that deform the graphene coating during the drying of the liquid trapped between the graphene and the substrate, revealing that Laplace's pressure can determine the degree of graphene adhesion to the substrate.
