▎ 摘  要

NOVELTY - Production of surface-metalized fiber, yarn, or fabric involves feeding a continuous fiber, yarn, or fabric from a feeder roller or spool into a graphene deposition chamber comprising a graphene dispersion containing multiple graphene sheets and an optional conducive filler dispersed in a liquid medium (l1) and an optional adhesive resin dissolved in the liquid medium (l1), operating the graphene deposition chamber, moving the obtained graphene-coated fiber, yarn, or fabric into a metallization chamber, and operating a winding roller to collect the surface-metalized fiber, yarn, or fabric. The multiple graphene sheets comprises single-layer or few-layer graphene sheets chosen from pristine graphene material comprising essentially 0 wt.% non-carbon elements and non-pristine graphene material comprising 0.001-25 wt.% non-carbon elements. The non-pristine graphene is at least one chosen from e.g. graphene oxide, graphene iodide, doped graphene and chemically functionalized graphene. USE - Production of surface-metalized fiber, yarn, or fabric used for decorative applications. Uses include but are not limited radiator grills, mirror caps, door handles, trim, food packaging bag, protective clothing, antistatic fabric or bag, susceptor in microwave cooking, blanket, anti-reflection fabric, children's toy, etc. ADVANTAGE - The method enables production of surface-metalized fiber, yarn, or fabric with improved scratch resistance, strength, hardness, electrical conductivity, thermal conductivity, light reflectivity, and gloss. DETAILED DESCRIPTION - Production of surface-metalized fiber, yarn, or fabric involves feeding a continuous fiber, yarn, or fabric from a feeder roller or spool into a graphene deposition chamber comprising a graphene dispersion containing multiple graphene sheets and an optional conducive filler dispersed in a liquid medium (l1) and an optional adhesive resin dissolved in the liquid medium (l1), operating the graphene deposition chamber 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, moving the graphene-coated fiber, yarn, or fabric 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, and operating a winding roller to collect the surface-metalized fiber, yarn, or fabric. The multiple graphene sheets comprises single-layer or few-layer graphene sheets chosen from pristine graphene material comprising essentially 0 wt.% non-carbon elements and non-pristine graphene material comprising 0.001-25 wt.% non-carbon elements. The non-pristine graphene is at least one chosen from graphene oxide, reduced graphene oxide, graphene fluoride, graphene chloride, graphene bromide, graphene iodide, hydrogenated graphene, nitrogenated graphene, doped graphene and chemically functionalized graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene-mediated metalized fiber.
