Abstract: The design of nanowires with intersecting spherical particles was carried out, after which the constructions determining the cellular structure of the flat web were made. The mathematical model presented in this paper is a classical model of the dynamics of molecules in potential fields of spherical particles. By systematic calculations it was established that in the case of a web composed of diamond threads the relative permeability of the structure is the relative area of the free passage zone of the nanowires cell, found from the effective radius of the nanowires. For a fabric made of diamond nanowires with a diameter of 0.7 nm, it is shown that there is no accumulation of gas components in the potential wells of the structure. Thus, the ideal carbon structure under consideration is "pure". This allows us to hope that the filtration regime of the gas components will be kinetic rather than diffusion. In this case, the network of diamond threads can serve as the main separation layer of the nanoporous membrane. Systematic calculations show that the relative permeability of a component, is the proportion of the area of the permeability window in the total area of the cell web.
