  • High thermal conductance thermal interface materials based on nanostructured metallic network-polymer composites
    Patent number: 9512291
    Abstract: A composite structure provides high thermal conductivity as a thermal interface structure with a relatively low filler loading. The composite structure is formed by dispersing nanoparticles in a matrix at a low filler loading, and controlled sintering of the composite structure to induce agglomeration of the nanoparticles into a connected percolating thermally conducting network structure within the matrix.
    Type: Grant
    Filed: May 14, 2015
    Date of Patent: December 6, 2016
    Assignees: INTERNATIONAL BUSINESS MACHINES CORPORATION, RENSSELAER POLYTECHNIC INSTITUTE
    Inventors: Theodorian Borca-Tasciuc, Sushumna Iruvanti, Fengyuan Lai, Kamyar Pashayi, Joel Plawsky, Hafez Raeisi-Fard

  • Siloxane optical waveguides
    Patent number: 6832036
    Abstract: Optical waveguide structures containing siloxane resin composistions as core materials and a method for preparing the waveguides are disclosed. The siloxane resin compositions can be cured by thermal energy or actinic radiation. In addition, conventional patterning techniques can be used, which makes the present method ideal for practicing on a commercial scale. The optical waveguides of the invention exhibit very low optical losses and are compatible with silicon processing requirements, which makes them useful in integrated circuitry. In addition, the high refractive index contrasts between the siloxane resin core and various claddings, including other siloxane resins, makes the waveguides particularly desirable.
