Title:
METHOD FOR MANUFACTURING METAL NANOPARTICLES BY USING PHASE TRANSITION REDUCTION, AND METAL INK COMPRISING METAL NANOPARTICLES MANUFACTURED THEREBY
Document Type and Number:
WIPO Patent Application WO/2014/030826
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing metal nanoparticles by using phase transition reduction, in which a reduction reaction is controlled by a distribution balance of an intermediate that is formed as a result of covalent bonding of a variety of metal precursors in an organic phase and a capping material, and by reducing agents in a water phase, and to a metal ink which is manufactured from the metal nanoparticles. The method according to the present invention comprises the steps of: dissolving the metal precursors and the capping material in an organic phase; dissolving the reducing agents in a water phase; mixing the organic phase and the water phase to form a precipitate; isolating the precipitate; and drying the isolated precipitate. The metal nanoparticles obtained thereby can be manufactured into metal nanoparticles having a variety of particle sizes, according to the type of precursor and the length of an alkyl chain of an amine that is used as a capping agent, and the particle sizes thereof are easily controlled due to a self-concluding reaction, which causes nanoparticles to settle from an organic layer into a water layer due to the difference in density of the nanoparticles that are produced during the reaction, thereby stopping the growth of the nanoparticles in the water layer.
