Abstract
Provided is a graphene foam-based sealing material comprising: (a) a graphene foam framework comprising pores and pore walls, wherein the pore walls comprise a 3D network of interconnected graphene planes or graphene sheets; and (b) a permeation-resistant binder or matrix material that coats and embraces the exterior surfaces of the graphene foam framework and/or infiltrates into pores of the graphene foam, occupying from 10% to 100% (preferably from 10% to 98% and more preferably from 20% to 90%) of the pore volume of the graphene foam framework.
