METHOD FOR PREPARING COMPOSITE OF NANO-METAL AND CARBON NANOMATERIAL

Document Type and Number:

WIPO Patent Application WO/2016/052890

Kind Code:

A2

Abstract:

The subject matter of the present invention is a method for preparing a composite of a nano-metal and a carbon nanomaterial, comprising the steps of: modifying the surface of a carbon nanomaterial in order to introduce a functional group into a conductive carbon nanomaterial; forming a carbon nanomaterial dispersion solution, which is reactive with metal ions, by mixing the surface-modified carbon nanomaterial with an isocyanate-based compound and a pyrimidine-based compound and reacting the same; preparing metal nanoparticles by adding a metal salt precursor, a reducing agent and a solvent to the carbon nanomaterial dispersion solution; and separating the metal nanoparticles containing the carbon nanomaterial. Accordingly, a nano-metal exhibiting a low dimensional shape less than a three-dimension can be obtained by mixing a carbon nanomaterial with an isocyanate-based compound and a pyrimidine-based compound and reacting the same so as to use the carbon nanomaterial, which is reactive with metal ions, as an additive. In addition, there is an effect of greatly facilitating the preparation of a conductive ink or paste since compositing with a carbon nanomaterial is performed simultaneously with the formation of a nano-metal, and solvent dispersibility is ensured by a functional group formed by mixing and reacting an isocyanate-based compound and a pyrimidine-based compound.
