Claim:
1. A graphene-based foam, the graphene-based foam having a structure defined by a three-dimensional network of interconnected and ordered open cells, the open cells being defined by cell walls, the cell walls (i) being formed of graphene sheets, partially reduced graphene oxide sheets, reduced graphene oxide sheets, or a combination thereof, (ii) having a thickness defined by the thickness of a plurality of graphene sheets, partially reduced graphene oxide sheets, reduced graphene oxide sheets, or a combination thereof, and (iii) having an average height that is 100 to 5000 times greater than the average cell wall thickness, wherein the graphene-based foam has a compression set at 50% compression of 15% or less, wherein the graphene-based foam has an average cell wall thickness of about 2 nm to 1000 nm.
