  • HIGHLY CONDUCTIVE ELECTRICALLY CONDUCTIVE ADHESIVES
    Publication number: 20130056689
    Abstract: The present invention provides for a relatively simple method to decrease the electrical resistivity of conductive adhesives by in-situ nanoparticle formation and sintering using a reducing agent. The reducing agent was found to cause sintering within the conductive adhesive by facilitating the reduction of the silver salts of fatty acids on the surface of silver flakes, leading to the formation of nano-/submicron-silver necks. These silver necks bridge neighboring silver flakes, decreasing the contact resistance between flakes within the conductive adhesives. The reducing agent also removes at least a portion of the lubricant commonly found on silver flakes used in conductive adhesives, thus reducing the tunneling resistance between the silver flakes.

    Publication number: 20130045416
    Abstract: Synthesis of gold microtubes and nanotubes suspendable in solution is presented. The synthesis is accomplished using an AAO template route, wherein a polymer tube is used as a sacrificial core. The synthesis produces hollow structures that consist of only gold. These nanostructures exhibit two SPR modes, which correspond to both the transverse and longitudinal modes. The mode assignment was confirmed by measuring SPR behavior as both aligned arrays and in solution. The performance of gold nanotubes as refractive index detectors was quantified and determined to be more sensitive than analogous solid nanorods prepared under identical conditions, and are among the most sensitive nanostructured plasmon sensors to date. Due to their intense and sensitive resonances in the NIR spectrum, these solution-suspendable nanoparticles have potential to be used as in vitro or in vivo sensors.

  • Thermosetting adhesive compositions
    Patent number: 8378017
    Abstract: The invention is based on the discovery that adhesive compositions containing certain low-viscosity, mono-ethylenically unsaturated monomers have surprisingly good cure parameters, resulting in very little weight loss upon cure. Many of these monofunctional monomers used alone or in combination with other monofunctional monomers described herein have high glass transition temperatures when cured. Moreover, since these monomers are monofunctional the crosslink density of the adhesive composition does not increase (relative to multi-functional monomers), which in turns results in lower stress, lower modulus adhesive compositions. As such, these monomers are useful in a variety of thermoset adhesive compositions, such as for example, die attach adhesive compositions.
