▎ 摘　　要

NOVELTY - A graphene compound comprises optionally functionalized graphene directly bonded to nitrogen-containing compound. USE - A graphene compound for barrier element and clear packaging for product (all claimed). ADVANTAGE - The graphene compound has strong gas, fluid, and/or vapor barrier properties, high mechanical strength, excellent flexibility, and low cost, and is metal-free and microwaveable. DETAILED DESCRIPTION - A graphene compound comprises optionally functionalized graphene directly bonded to nitrogen-containing compound of formula -NH-R-NHCOR' or -CO-NH-R-NHCOR'. R=optionally substituted 1-20C hydrocarbylene; and R'=optionally substituted 1-30C hydrocarbyl or 3-30C heteroaryl. INDEPENDENT CLAIMS are included for: (1) barrier element comprising graphene compound, in which barrier element is transparent; and (2) product wrapped in clear packaging.
