Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. 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, wherein the composition of matter has a gas permeability less than 0.01 cc·mil/100 in 2 /24 h/atm and outgassing properties of CVCM of less than 0.1 percent and TML less than 1 percent. 2. The object of claim 1 wherein the composition of matter consists of chemically bonded horizontally aligned graphene sheets bonded by epoxy linkers. 3. 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, wherein the composition of matter consists of non-functionalized graphene sheets dispersed in low outgassing epoxy.
