Embodiment 1

[0042] In a round bottom flask, 50 mL of silver nitrate (AgNO 3 ) dissolved in ethylene glycol to form a solution with a concentration of 0.1M and 50mL of 1-butyl-3-methylimidazolium methyl sulfate (1-butyl-3-methylimidazolium methyl sulfate) dissolved in ethylene glycol to form a concentration The 0.15 M solutions were mixed to form a mixed solution. Subsequently, the mixed solution was stirred and allowed to react at a temperature of 160° C. for 60 minutes, and then cooled to room temperature. Subsequently, the cooled mixed solution was filtered with a filter having a pore size of 1 μm, and then observed with a scanning electron microscope. As a result, metal nanowires formed, such as figure 1 shown. It can be observed that the metal nanowires have a diameter of about 220 nm and a length of about 7 μm.

Embodiment 2

[0044] In a round bottom flask, 10 mL of silver nitrate (AgNO 3 ) was dissolved in 1,3-propanediol to form a solution with a concentration of 0.2M and 10 mL of 1-ethyl-3-methylimidazolium methyl sulfate (1-ethyl-3-methylimidazolium methyl sulfate) was dissolved in 1,3- A solution with a concentration of 0.3 M in propylene glycol was mixed to form a mixed solution. Subsequently, the mixed solution was stirred and allowed to react at a temperature of 100° C. for about 30 minutes, and then cooled to room temperature. Subsequently, the cooled mixed solution was filtered with a filter having a pore size of 1 μm, and then observed with a scanning electron microscope. As a result, it was found that the formed metal nanowires had a diameter of about 180 nm and a length of about 10 μm.

Embodiment 3

[0046] In a round bottom flask, 10 mL of silver nitrate (AgNO 3 ) dissolved in 1,2-propylene glycol to form a solution with a concentration of 0.2M and 10 mL of 1-ethyl-3-methylimidazolium methyl sulfate dissolved in 1,3-propylene glycol to form a solution with a concentration of 0.3M. to form the first mixed solution, followed by silver nitrate (AgNO 3 ), sodium lauryl sulfate was added into the first mixed solution to form the second mixed solution. Subsequently, the second mixed solution was stirred and reacted at a temperature of 100° C. for about 30 minutes, and then cooled to room temperature. Subsequently, the cooled mixed solution was filtered with a filter having a pore size of 1 μm, and then observed with a scanning electron microscope. As a result, it was found that the formed metal nanowires had a diameter of about 80 nm and a length of about 10 μm.

Abstract

The present invention relates to a production method for a nano-scale metal structure, and more specifically to a method for uniformly producing metal nanostructures of various forms such as cubic and octahedral and wires, by using an ionic liquid in a polyol reduction reaction using a metallic salt as a precursor.

Description

technical field [0001] The present invention relates to a method of forming metal nanostructures, and more particularly to a method of using ionic liquids in polyol reduction reactions using metal salts as precursors to uniformly form nanoparticles of various shapes such as cubes or octahedrons, nanowires, and Analogous nanostructuring methods. Background technique [0002] Recently, studies on the synthesis of metal nanoparticles have been actively conducted in order to apply them to flat panel displays, touch panels, solar cells, and the like. Since these metal nanoparticles can actually be used to manufacture transparent electrodes, conductive inks, and the like, it is necessary to develop a technology that can mass-produce the metal nanoparticles. Further, since the shape of metal nanoparticles is an important factor affecting material properties such as electrical conductivity and the like, it is also necessary to develop a technology that can freely control the shape ...
