Carbon nanomaterials present new possibilities for creating permeable membranes. Ionic beam etching technology allows to create pores in graphene substrates and has the potential to be used in various separation processes. In our study we present a molecular dynamics simulation of the energy needed to puncture the graphene surface to create porous surface. Experimental part shows dependency of irradiation time to pore diameter on silica substrate, which indicates it is possible to create pore diameters lesser than the beam diameter. We present a technology process of creating pores of a specific diameter.
