The polymer-based material comprises metal particles dispersed in a matrix material. The metal particles are encapsulated by a dielectric coating so that they are electrically insulated from each other. The polymer-based material may also comprise dielectric particles dispersed in the matrix material and/or the dielectric coating for the purpose of further increasing the thermal conductivity of the polymer-based material. The material is also suitable for use as a potting compound or an encapsulation material for various electronic applications.

  • Patent number: 6608129
    Abstract: Composites which include a polymer matrix having natural free volume therein and an inorganic or organic material disposed in the natural free volume of the polymer matrix are disclosed. In addition, methods for making a composite are described. A polymer matrix having free volume therein is provided. The free volume is evacuated, and inorganic or organic molecules are infused into the evacuated free volume of the polymer matrix. The inorganic or organic molecules can then be polymerized under conditions effective to cause the polymerized inorganic or organic molecules to assemble into macromolecular networks. Alternatively, where the polymer matrix contains a functionality, the inorganic or organic molecules can be treated under conditions effective to cause the inorganic or organic molecules to interact with the polymer matrix's functionality.

  • Patent number: 6599965
    Abstract: The invention provides a coating composition for use with metallic substrates that provides a unique balance of required properties. In particular, the coating composition of the invention simultaneously provides desirable levels of adhesion to metal, sandability without the production of harmful dust, corrosion resistance, and recoatability. The coating composition of the invention comprises a polyurethane or epoxy/amine film-forming component, and a corrosion protection component consisting of aluminum selected from the group consisting of nonleafing aluminum pigments, the corrosion protection component being present in the composition in an amount effective to prevent corrosion of the substrate. A cured film of the coating applied to a steel substrate has a pass rating after 480 hours in salt spray per ASTM B117.

  • Patent number: 6593410
    Abstract: In this method for making a sintered reactive material, fuel particles are blended with a polymer matrix comprising at least one fluoropolymer in an inert organic media to disperse the fuel particles in the polymer matrix and form a reactive material. The reactive material is dried and pressed to obtain a shaped pre-form, which is sintered in an inert atmosphere to form the sintered reactive material. By sintering in an inert atmosphere, the sintered reactive material may include reactive metals and/or metalloids in a non-oxidized state. The resulting sintered reactive material preferably has a tensile strength in excess of 1800 psi and an elongation at break in excess of 30%.
