In this paper, sandwich structures for the separation of gas mixtures are considered. As a result, two types of structures were created and tested: a model complex structure based on a carbon nanotube and a graphene sheet, which consisted of 360 carbon atoms and a sandwich structure composed of a graphene sheet and two parallel carbon nanotubes. The results show that some materials collected from such cell structures can potentially be used for the separation of methane-helium mixtures. The results of calculations for methane and helium are presented.
