NOVELTY - An adhesive comprises adhesive main blank, and 0.2-1 wt.% graphene. USE - Adhesive for capsule material (claimed) of airship spacecraft. ADVANTAGE - The adhesive has excellent helium blocking performance due to the presence of graphene. The adhesive provides lightweight airship capsule material due to the presence of low graphene which prevents increase in surface density and processing complexity of capsule material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the adhesive, which involves dispersing graphene in adhesive main blank; and (2) capsule material, which comprises one or more adhesive layers comprising at least one of the adhesive.
