Problems solved by technology

But most of the methods are complex, difficult to operate, high energy consumption, unstable quality, low yield and uneven
Such as the patent of Duke University, the patent number is CN102787347A. To prepare gram-level copper wire, a large amount of pharmaceutical reagents are required to be produced in a rather large container, which is very wasteful and difficult to operate.

Embodiment 1

[0027] Add 35 ml of water into the beaker, add 3.72 g (0.01 mol) of EDTA-2Na (disodium ethylenediamine tetraacetate), add 1.6 g of copper sulfate (0.01 mol), and stir well. Then 1.4 g (0.01 mol) of urotropine and 0.8 g of CTAB (cetyltrimethylammonium bromide) were added in sequence and stirred evenly to obtain a mixed solution.

[0028] The mixed solution was placed in an autoclave for hydrothermal reaction at 150° C. for 120 hours. After the reaction, the precipitate was collected by centrifugation, washed three times with absolute ethanol, then washed three times with deionized water, and dried at 30° C. for 12 hours to obtain material 1.

[0029] From Figure 7 It can be seen that material 1 is pure copper with extremely high crystallinity. From figure 1 It can be seen that the copper micron wire of material 1 is a regular pentagonal column structure; from figure 2 It can be seen that the length of the copper micron line of material 1 is between 200 and 300 microns, w...

[0032] Add 35 ml of water into the beaker, add 3.72 g (0.01 mol) of EDTA-2Na (disodium ethylenediamine tetraacetate), add 0.005 mol of copper nitrate, and stir well. Then 0.70 g (0.005 mol) of urotropine and 0.4 g of CTAB (cetyltrimethylammonium bromide) were added in sequence and stirred evenly to obtain a mixed solution.

[0033] The mixed solution was placed in an autoclave for hydrothermal reaction at 135° C. for 144 hours. After the reaction, the precipitate was collected by centrifugation, washed three times with absolute ethanol, then washed three times with deionized water, and dried at 80° C. for 0.5 hour to obtain material 2.

[0034] The X-ray electron diffraction image of material 2 shows that material 2 is pure copper with extremely high crystallinity. From image 3 It can be seen that the copper micron wire of material 2 is a regular pentagonal prism structure, from Figure 4 It can be seen that the length of material 2 is between 200 and 300 microns, which is...

[0038] Add 35 ml of water into the beaker, add 3.72 g (0.01 mol) of EDTA-2Na (disodium ethylenediamine tetraacetate), add 2.4 g of copper sulfate (0.015 mol), and stir well. Then 2.1 g (0.015 mol) of urotropine and 1.2 g of CTAB (cetyltrimethylammonium bromide) were added in sequence and stirred evenly to obtain a mixed solution.

[0039] The mixed solution was placed in an autoclave for hydrothermal reaction at 180° C. for 100 hours. After the reaction, the precipitate was collected by centrifugation, washed three times with absolute ethanol, then washed three times with deionized water, and dried at 55° C. for 6 hours to obtain material 3.

Abstract

The invention provides a preparation method of a regular pentagonal prism-shaped copper micrometer wire, and relates to preparation methods of micrometer nanoelectrode materials. The preparation method comprises the following steps: EDTA-2Na and copper salt are dissolved in water, urotropin and CTAB are sequentially added at the time of stirring, and a mixed solution is obtained after uniform stirring; the mixed solution is placed in a high pressure reactor for a reaction on the condition of 120-200 DEG C for 24-240 hours; after the reaction is over, sediment is extracted through a centrifugal effect, washed and dried to obtain the regular pentagonal prism-shaped copper micrometer wire. According to the preparation method, chemicals low in cost are used; compared with most copper wire preparation methods, the preparation method has the advantages of being simple, easy to operate, high in yield, low in pollution, low in energy consumption, economical and environmentally friendly since raw materials can be recovered, and the like.

Description

technical field [0001] The invention relates to the field of electrode materials, in particular to a method for preparing regular pentagonal copper micron wires. Background technique [0002] Copper micron wire has the advantages of good electrical conductivity, thermal conductivity, corrosion resistance, and non-magnetic properties of metallic copper. As a functional material, copper micron wire can also be applied to electrical contact materials, conductive materials, diamond products and mechanical parts, etc., and Emerging petroleum catalysts, lubricants, conductive and decorative coatings and electromagnetic shielding materials, etc. [0003] The main production methods of copper wire are vapor deposition, electrochemical deposition, sol-gel method, hydrothermal method and so on. But most of the methods are complex, difficult to operate, high energy consumption, unstable quality, low and uneven yield. Such as the patent of Duke University, the patent number is CN10278...
