    摘要: An apparatus and method for enhancing the surface energy and/or surface chemistry of carbon fibers involves exposing the fibers to direct or indirect contact with atmospheric pressure plasma generated using a background gas containing at least some oxygen or other reactive species. The fiber may be exposed directly to the plasma, provided that the plasma is nonfilamentary, or the fiber may be exposed indirectly through contact with gases exhausting from a plasma discharge maintained in a separate volume. In either case, the process is carried out at or near atmospheric pressure, thereby eliminating the need for vacuum equipment. The process may be further modified by moistening the fibers with selected oxygen-containing liquids before exposure to the plasma.

    摘要: A method for fabricating a heat sink may include: providing a carbon fiber fabric having carbon fibers and openings, the openings leading from a first side to a second side of the fabric; and electroplating the fabric with metal, wherein metal is deposited with a higher rate at the first side than at the second side of the fabric. Another method for fabricating a heat sink may include: providing a carbon metal composite having metal-coated carbon fibers and openings, the openings leading from a first side to a second side of the carbon metal composite; disposing the composite over a semiconductor element such that the first side of the composite faces the semiconductor element; and bonding the composite to the semiconductor element by means of an electroplating process, wherein metal electrolyte is supplied to an interface between the carbon metal composite and the semiconductor element via the openings.

    摘要: An article is provided that includes a polymeric fiber that has an excess number of surface active reactive moieties relative to the number of surface reactive moieties found on the fiber in a native state. A particle is bonded covalently to the fiber through an intermediate coupling agent. Multiple particles can be covalently bonded to the fiber, the multiple particles can be bonded uniformly or asymmetrically around the fiber diameter. A process for modifying a fiber includes creating surface activated reactive moieties thereon. The activated fiber is then exposed to a liquid solution containing a coupling agent to form a covalent bond. The coupling agent is also reacted with a particle in a liquid solution to form a covalent bond between the coupling agent and the particle. The coupling agent is covalently bonded to either a particle and then bonded to the fiber, or vice versa.
