NANOMETAL-NANOCARBON HYBRID MATERIAL AND METHOD OF MANUFACTURING THE SAME

摘要

Disclosed are a nanometal-nanocarbon hybrid material and a method of manufacturing the same, the method including modifying the surface of nanocarbon to introduce a functional group to conductive nanocarbon; mixing the surface-modified nanocarbon with an isocyanate-based compound and a pyrimidine-based compound and allowing them to react, thus forming a nanocarbon dispersion reactive to metal ions; adding the nanocarbon dispersion with a metal salt precursor, a reducing agent and a solvent, thus manufacturing nanometal particles; and separating a hybrid of the nanometal particles having the nanocarbon bound thereto. Thereby, nanocarbon is mixed with an isocyanate-based compound and a pyrimidine-based compound and then allowed to react, whereby the nanocarbon reactive with metal ions is used as an additive, thus obtaining a nanometal having a low-dimensional shape having less than three dimensions. Also, a nanometal can be hybridized with nanocarbon simultaneously with the formation of the nanometal, and solvent dispersibility is ensured by a functional group formed by mixing and reacting an isocyanate-based compound and a pyrimidine-based compound, ultimately facilitating the preparation of conductive ink or paste.
