  • Polymer-inorganic particle composites
    Patent number: 7792406
    Abstract: Inorganic particle/polymer composites are described that involve chemical bonding between the elements of the composite. In some embodiments, the composite composition includes a polymer having side groups chemically bonded to inorganic particles. Furthermore, the composite composition can include chemically bonded inorganic particles and ordered copolymers. Various electrical optical and electro-optical devices can be formed from the composites.
    Type: Grant
    Filed: April 4, 2005
    Date of Patent: September 7, 2010
    Assignee: NanoGram Corporation
    Inventors: Nobuyuki Kambe, Yigal Dov Blum, Benjamin Chaloner-Gill, Shivkumar Chiruvolua, Sujeet Kumar, David Brent MacQueen
