    摘要： The present disclosure is generally directed to a variety of thermally conductive materials for use in semiconductor devices or other applications. In some cases, the materials may include aligned fibers such as carbon fibers, e.g., defining a substrate, and a metal such as solder. In some cases, the metal may be present within a transition metal rich solder alloy, a conductive medium such as a conductive ink, a thermal chemical vapor deposited solder, an oxide coated liquid metal, an oxide coated liquid metal transition metal rich solder alloy, etc. The metal may have a relatively low melting temperature in certain embodiments. The metal may be interspersed or infiltrated between the plurality of discontinuous fibers, and/or surround at least some of the fibers. In some cases, the metal may react with the carbon fibers to form metal carbides and/or diffuse into the carbon fibers, which may facilitate contact between the metal and the carbon fibers. Other aspects are generally directed to devices using such compositions, methods of making such compositions, kits including such compositions, or the like.

    摘要： A process to clean carbon fiber fabric of a pre-applied sizing, while simultaneously activating or preparing the fabric to receive a polymer resin is described. The cleaning process and chemistry combines an enzymatic cleaning solution with an oxidizing agent. The enzymatic solution strips the fibers of lubricants, surfactants, and other chemicals of the sizing which might otherwise interfere with interfacial properties and bonding of the fabric to the matrix resin. The inclusion of an oxidizing agent concurrently adds hydroxyl groups to the surface of the fabric allowing for the grafting of organic copolymers to the surface of the fabric, the copolymer being chosen based upon the desired polymer resin. This process provides a customized finished carbon fiber fabric to bond to a specific polymer resin, without interference resulting from an inadequate fiber sizing chemistry. In this way, a customizable finished fabric may be manufactured.
