  • Metal nanoparticle compositions
    Publication number: 20060189113
    Abstract: A metal nanoparticle composition for the fabrication of conductive features. The metal nanoparticle composition advantageously has a low viscosity permitting deposition of the composition by direct-write tools. The metal nanoparticle composition advantageously also has a low conversion temperature, permitting its deposition and conversion to an electrical feature on polymeric substrates.

  • Printable electrical conductors
    Publication number: 20060163744
    Abstract: An electrical conductor formed from one or more metallic inks. The electrical conductor comprises a network of interconnected metallic nodes. Each node comprises a metallic composition, e.g., one or more metals or alloys. The network defines a plurality of pores having an average pore volume of less than about 10,000,000 nm3. The electrical conductors advantageously have a high degree of conductivity, e.g., a resistivity of not greater than about 10× the resistivity of the (bulk) metallic composition, which forms the individual nodes.

  • Separation of metal nanoparticles
    Publication number: 20060159603
    Abstract: A process for the production of metal nanoparticles. Nanoparticles are formed by combining a metal compound with a solution that comprises a polyol and a substance that is capable of being adsorbed on the nanoparticles. The nanoparticles are precipitated by adding a nanoparticle-precipitating liquid in a sufficient amount to precipitate at least a substantial portion of the nanoparticles and of a protic solvent in a sufficient amount to improve the separation of the nanoparticles from the liquid phase.

  • Precursor compositions for the deposition of electrically conductive features
    Publication number: 20060043346
    Abstract: A precursor composition for the deposition and formation of an electrical feature such as a conductive feature. The precursor composition advantageously has a viscosity of at least about 1000 centipoise and can be deposited by screen printing. The precursor composition also has a low conversion temperature, enabling the deposition and conversion to an electrical feature on low temperature substrates. A particularly preferred precursor composition includes silver and/or copper metal for the formation of highly conductive features.
