▎ 摘  要

NOVELTY - Producing surface-metalized fiber, yarn, or fabric involves preparing a graphene dispersion comprising multiple graphene sheets and an optional conductive filler dispersed in a first liquid medium, which is an adhesive monomer or contains a liquid adhesive monomer or oligomer dissolved in a solvent. A continuous fiber, yarn, or fabric from a feeder roller or spool is fed into a graphene deposition zone, where the graphene dispersion is sprayed, painted, coated, cast, or printed to deposit the graphene sheets and optional conductive filler to a surface of the fiber, yarn, or fabric for forming a graphene-coated fiber, yarn, or fabric. The graphene-coated fiber, yarn, or fabric is moved into a metallization chamber which accommodates a plating solution for plating a layer of a desired metal onto the graphene-coated fiber, yarn, or fabric to obtain a surface-metalized fiber, yarn, or fabric. USE - Method for producing surface-metalized fiber, yarn, or fabric. DETAILED DESCRIPTION - Producing surface-metalized fiber, yarn, or fabric involves preparing a graphene dispersion comprising multiple graphene sheets and an optional conductive filler dispersed in a first liquid medium, which is an adhesive monomer or contains a liquid adhesive monomer or oligomer dissolved in a solvent. A continuous fiber, yarn, or fabric from a feeder roller or spool is fed into a graphene deposition zone, where the graphene dispersion is sprayed, painted, coated, cast, or printed to deposit the graphene sheets and optional conductive filler to a surface of the fiber, yarn, or fabric for forming a graphene-coated fiber, yarn, or fabric. The graphene-coated fiber, yarn, or fabric is moved into a metallization chamber which accommodates a plating solution for plating a layer of a desired metal onto the graphene-coated fiber, yarn, or fabric to obtain a surface-metalized fiber, yarn, or fabric. A winding roller is operated to collect the surface-metalized fiber, yarn, or fabric. The multiple graphene sheets contain single-layer or few-layer graphene sheets selected from a pristine graphene material having essentially zero % of non-carbon elements, or a non-pristine graphene material having 0.001-25% by weight of non-carbon elements where the non-pristine graphene is selected from graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene, chemically functionalized graphene, or a combination.
