INVESTIGATING PERMEABILITY OF POROUS GRAPHENE

ABSTRACT
A graphene sheet with regular pores similar to the surface form of boron nitride is simulated be means of crystallographic constructions. The sheet is represented by the aggregate of carbon atoms in the corresponding positions of the crystal structure which do not experience thermal oscillations. Within the framework of the presented approximation, permeability of porous graphene with respect to natural gas components is theoretically analysed. Based on the results obtained, selectivity of separation for methane-helium mixtures is determined.
