▎ 摘　　要

NOVELTY - A gas barrier composite comprises a polymer matrix and graphene nanoribbon dispersed in the polymer matrix. USE - Gas barrier composite. Uses include but are not limited to lightweight mobile gas storage container, inflatable rafts, inflatable slides, children's play toys, inflatable signs, inflatable boats, safety air bags for vehicles, balloons, gas tanks and gas cylinders etc. ADVANTAGE - The gas barrier composite has low gas permeability, excellent mechanical property and thermal stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of gas barrier composite. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining the preparation process of gas barrier composite.
