LOW VOLATILITY, HIGH EFFICIENCY GAS BARRIER COATING FOR CRYO-COMPRESSED HYDROGEN TANKS

A bilayer object consisting of a carbon fiber reinforced polymer substrate coated with a composition of matter comprising horizontally aligned exfoliated graphene sheets dispersed in an epoxy binder. A method includes depositing graphene into a hardener, mixing the hardener and the graphene to produce a homogenous composite mixture, adding a resin material to the composite mixture to produce an epoxy graphene material, coating a structure with the epoxy graphene material, aligning the graphene sheets in the in-plane orientation, and curing the epoxy graphene material.
