Abstract
A gas barrier material includes an atomic sheet, such as graphene and/or an analog of graphene. The gas barrier material can be arranged as part of a component, such as a container or other vessel, to limit the flow or permeation of gas through the component. Where the component is a container or part of a container, the gas barrier material may be formulated and arranged to limit or prevent gas ingress or egress with respect to the internal volume of the container. The atomic sheet offers improved gas barrier properties compared to traditional polymeric barrier materials and is particularly useful in applications where it is desired to limit permeation of small gas molecules such as helium, such as airships or other lighter than air vehicles.
