The present invention relates to: a paste composition including ceramic particles surface-functionalized with an amine group and a maleic anhydride-grafted elastomer; and a preparation method therefor and, to: a paste composition enabling ceramic particles to have a high content and be highly dispersed, thereby enabling the composition to have a high generation capacity when a device is manufactured; and a preparation method therefor.

Paste composition and preparation method therefor

An ink composition for photonic sintering and a method or producing the ink composition, the ink composition includes: metal nanoparticles comprising a first metal satisfying interaction formula 1; an organic non-aqueous binder; and a non-aqueous solvent. Interaction formula 1 is A1/A2&#x2264;0.2, where A1/A2 is a ratio, in the x-ray photoelectron spectrum on the surface of the first metal, in which first metal 2p3/2 peak area of the oxide of the first metal (A1) is divided by first metal 2p3/2 peak area of the first metal (A2).

Ink composition for photonic sintering and method for producing same

Metal nanoparticles according to the present invention have at least a bimodal size distribution in which the ratio obtained by dividing the area of a first peak, which has the smallest median size on the basis of the median size of peaks in the size distribution of the metal nanoparticles, by the total area of all peaks constituting the size distribution meets 0.4-0.8, and are capped with a capping layer containing an organic acid.

Metal nanoparticles, and preparation method therefor

Provided is a method of manufacturing a conductive metal thin film, the method including: a) heating and stirring a first solution containing a metal precursor, acid, amine, and a reducing agent to synthesize metal nano-particles on which formation of a surface oxide film is suppressed; b) dispersing the metal nano-particles synthesize in step a) in a non-aqueous solvent to prepare a conductive ink composition; c) applying the conductive ink composition onto an insulating substrate; and d) heat-treating the insulating substrate applied with the ink composition to form a conductive metal thin film. With the method of manufacturing a conductive metal thin film according to the present invention, large area conductive thin film may be manufactured as compared with the existing conductive ink composition based on noble metal nano-particles. In addition, the conductive metal thin film having excellent conductivity may be manufactured by suppressing a surface oxide film from being formed.
