US 7,820,097 B2 · Electrical, plating and catalytic uses of metal nanomaterial compositions

Abstract

This invention relates generally to uses of novel nanomaterial composition and the systems in which they are used, and more particularly to nanomaterial compositions generally comprising carbon and a metal, which composition can be exposed to pulsed emissions to react, activate, combine, or sinter the nanomaterial composition. The nanomaterial compositions can alternatively be utilized at ambient temperature or under other means to cause such reaction, activation, combination, or sintering to occur.

Dependent claims

A method for sintering materials comprising:

depositing a material on a substrate, wherein said substrate has a decomposition temperature below 450 degrees Celsius, wherein said material has at least one dimension less than 1 micrometer, wherein said material includes at least one metal;
and
irradiating said material on said substrate in ambient air by a flash lamp for sintering said material on said substrate, for a duration between one microsecond and one hundred milliseconds such that the conductivity of said material on said substrate increases by at least two-fold.

Dependencies are inferred from the claim text.
