To prepare a nerve guidance conduit, porous polymer sheet is prepared by a solvent casting method while using a template of thin rods to form parallel channels on a surface of the sheet. Aligned nanofibers are deposited on the sheet parallel to the channels. The polymer sheet is then wound to form a spiral structure. A dense layer of randomly-oriented nanofibers may be deposited on the outside of the spiral.

  • Patent number: 8808607
    Abstract: A thermally conductive sheet has cut surfaces with low surface roughness and hence shows reduced thermal resistance at the interfaces, and high thermal conductivity in the thickness direction. Thus, the thermally conductive sheet can be interposed between any of various heat sources and a radiation member. The process for producing the thermally conductive sheet includes at least: an extrusion molding step in which a thermally conductive composition containing a polymer, an anisotropic thermally conductive filler, and a filler is extruded with an extruder to thereby mold an extrusion-molded product in which the anisotropic thermally conductive filler has been oriented along the extrusion direction; a curing step in which the extrusion-molded product is cured to obtain a cured object; and a slicing step in which the cured object is sliced into a given thickness with an ultrasonic cutter in the direction perpendicular to the extrusion direction.

  • Publication number: 20140217574
    Abstract: A method for enhancing internal layer-layer thermal interface performance and a chip stack of semiconductor chips using the method. The method includes adding a thermosetting polymer to the thermal interface material, dispersing a plurality of nanofibers into the thermal interface material, and un-crosslinking the thermosetting polymer in the thermal interface material. The method further includes extruding the thermal interface material through a die to orient the conductive axis of the nanofibers and polymer chains in the desired direction, and re-crosslinking the thermosetting polymer in the thermal interface material. The chip stack includes a first chip with circuitry on a first side, a second chip coupled to the first chip by a grid of connectors, and a thermal interface material pad between the chips. The thermal interface includes nanofibers and a polymer that allows for optimal alignment of the nanofibers and polymer chains.
