  • Patent number: 10180288
    Abstract: A thermally-conductive and mechanically-robust bonding method for attaching a metal nanowire (MNW) array to an adjacent surface includes the steps of: removing a template membrane from the MNW; infiltrating the MNW with a bonding material; placing the bonding material on the adjacent surface; bringing an adjacent surface into contact with a top surface of the MNW while the bonding material is bondable; and allowing the bonding material to cool and form a solid bond between the MNW and the adjacent surface. A thermally-conductive and mechanically-robust bonding method for attaching a metal nanowire (MNW) array to an adjacent surface includes the steps of: choosing a bonding material based on a desired bonding process; and without removing the MNW from a template membrane that fills an interstitial volume of the MNW, depositing the bonding material onto a tip of the MNW.

  • Patent number: 9810820
    Abstract: A method for manufacturing optical and microwave reflectors includes: placing an assembly comprising a resin-infiltrated tendrillar mat structure on a mandrel; placing a pre-impregnated carbon fiber (CF) lamina on top of the tendrillar mat structure; placing the assembly in a vacuum device so as to squeeze out excess resin; and placing the assembly in a heating device so as to cure the tendrillar mat structure together with the CF lamina, forming the CF laminae into a laminate that combines with the tendrillar mat structure to create a cured assembly. A reflector suitable for one or more of optical and microwave applications includes: a mandrel; a resin-infiltrated tendrillar mat structure placed on the mandrel; and a pre-impregnated carbon fiber (CF) lamina placed on top of the tendrillar mat structure.

  • Patent number: 9741636
    Abstract: A thermal interface material (TIM) using high thermal conductivity nano-particles, particularly ones with large aspect ratios, for enhancing thermal transport across boundary or interfacial layers that exist at bulk material interfaces is disclosed. The nanoparticles do not need to be used in a fluid carrier or as filler material within a bonding adhesive to enhance thermal transport, but simply in a dry solid state. The nanoparticles may be equiaxed or acicular in shape with large aspect ratios like nanorods and nanowires.
