Fabric of continuous graphene fiber yarns from functionalized graphene sheets

A fabric comprising multiple yarns combined to form the fabric wherein at least one of said yarns comprises one or a plurality of graphene-based long or continuous fibers, wherein said graphene-based long or continuous fiber comprises chemically functionalized graphene sheets that are chemically bonded or interconnected with one another having an inter-planar spacing d002 from 0.36 nm to 1.5 nm as determined by X-ray diffraction and a non-carbon element content of 0.1% to 47% by weight, wherein said functionalized graphene sheets are substantially parallel to one another and parallel to a fiber axis direction and said fiber contains no core-shell structure, has no helically arranged graphene domains, and has a length no less than 0.5 cm and a physical density from 1.5 to 2.25 g/cm3, wherein said functionalized graphene sheets are interconnected with one another via chemical bonding or reactions between chemically active functional groups attached to respective adjacent functional groups in a face-to-edge manner and an edge-to-edge manner, wherein the graphene-based long or continuous fiber comprises a combination of sp2 and sp3 electronic configurations.
