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.

What is claimed is: 
     
         1 . A system for sintering materials, said system comprising:
 a flashlamp generates a plurality of electromagnetic emission pulses for irradiating a film on a substrate in ambient air in order to sinter said film on said substrate such that the conductivity of said film on said substrate increases by at least two-fold, wherein said film includes at least one metal less than 1 micrometer; and   a control circuit controls said flashlamp to limit a duration of each of said electromagnetic emission pulses to be between one microsecond and one hundred milliseconds.   
     
     
         2 . The system of  claim 1 , wherein said system further includes a printer for printing said film on said substrate using a formulation having said one metal less than 1 micrometer. 
     
     
         3 . The system of  claim 2 , wherein said one metal is copper. 
     
     
         4 . The system of  claim 1 , wherein said substrate has a decomposition temperature below 450 degrees Celsius. 
     
     
         5 . The system of  claim 1 , wherein said substrate includes a substance selected from the group consisting of PET, polyester, plastics, polymers, resins, paper products, laminates and combinations thereof. 
     
     
         6 . The system of  claim 1 , wherein said flashlamp is a xenon flashlamp. 
     
     
         7 . The system of  claim 1 , wherein said system further includes a conveyor for moving said substrate.
