PROCESS FOR GRAPHENE-MEDIATED METALLIZATION OF FIBERS, YARNS, AND FABRICS
Provided is process for producing a surface-metalized fiber, yarn, or fabric, the process comprising: (a) Feeding a continuous fiber, yarn, or fabric from a feeder roller into a graphene deposition chamber containing therein a graphene dispersion comprising multiple graphene sheets and an optional conducive filler dispersed in a first liquid medium and an optional adhesive resin dissolved in the first liquid medium; (b) 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; (c) Moving the graphene-coated fiber, yarn, or fabric into a metallization chamber which accommodates a plating solution therein 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 (d) Operating a winding roller to collect the surface-metalized fiber, yarn, or fabric.
OPTICAL FIBER, OPTICAL SENSOR INCLUDING OPTICAL FIBER, METHOD OF MANUFACTURING OPTICAL FIBER, AND DEPOSITION APPARATUS THEREFOR
Disclosed is an optical fiber including a plasmonic optical filter with a closed curved shape provided at, at least portion thereof. A method of manufacturing the plasmonic optical filter includes a step of exposing a core, a step of forming a thin metal film on the core through physical vapor deposition while rotating the core in a circumferential direction after changing a rotation axis of the core, and a step of patterning nanopatterns on the cylinder-shaped thin metal film using focused ion beam technique assisted with endpoint detection method. Due to such constitutions, an active area to generate an optical signal for optical sensor can be increased.
