[0081] Preparation of Copper Nanomaterials
[0082] The present invention also provides a method for preparing the material as described above, characterized in that it comprises the steps of:
[0083] (1) In an inert medium, add alkali, copper salt and modifier, and mix thoroughly to form a reaction system with pH ≥ 11; preferably, the pH of the system ≥ 12, more preferably ≥ 13.
[0084] (2) Under an inert atmosphere, a reducing agent is added to the reaction system for reaction to obtain copper nanomaterials.
[0085] Wherein, the reaction medium may be a medium selected from (but not limited to) the following group: water, alcohol solvent, amide solvent, sulfoxide solvent, or a combination thereof;
[0086] The base is not particularly limited, and may be (but not limited to) a base selected from the group consisting of sodium hydroxide, potassium hydroxide, ammonia, or a combination thereof; preferably, the base is a strong base, with Keep the system pH in the desired r...
Embodiment 1
[0109] Add 2.42g of sodium hydroxide and 80mL of deionized water into the two-necked flask in sequence, and stir to dissolve all the sodium hydroxide; when the system is cooled to room temperature, add 20mL of copper nitrate solution with a concentration of 0.1M and 2.80g of glycine in sequence, and continue stirring; Then drop 50 μL of hydrazine hydrate solution with a concentration of 35%. When the system starts to change color, heat the system to 60-90°C and continue stirring for 30-60 minutes, and a red solid is formed. Then filter with a water-based microporous filter membrane with a diameter of 50 mm and a pore size of 0.45 μm, and wash with a large amount of deionized water to obtain copper nanowires.
Embodiment 2
[0111] The preparation method is basically the same as in Example 1, except that the added surface modifier is glycine with a mass of 6.28 g, and the obtained product is copper nanowires.
