Abstract

A carbon composite material, including a plurality of spaced graphene sheets, each respective sheet having opposed generally planar surfaces, and a plurality of functionalized carbonaceous particles. At least some functionalized carbonaceous particles are disposed between any two adjacent graphene sheets, and each respective at least some functionalized carbonaceous particle is attached to both respective any two adjacent graphene sheets. Each respective graphene sheet comprises at least one layer of graphene and at least portions of respective any two adjacent graphene sheets are oriented substantially parallel with one another.
