Embodiment 1
[0028] The preparation process flow chart of the micro-nanostructure porous copper powder involved in this embodiment is as follows figure 1 As shown, it specifically includes the following steps:
[0029] (1) Preparation of Cu-containing precursor body fluid: First, add 0.8 g of copper acetate monohydrate to a certain amount of deionized water; secondly, add an aqueous solution containing 1.6 g of sodium hydroxide to the above Cu 2+ In the ionic solution, a light blue emulsion was obtained; again, 5 mL of ethylene glycol was added to the above solution; finally, a certain amount of deionized water was added to make the total volume 40 mL. Stir continuously during the whole process, and finally stir for about 1 h.
[0030] (2) Put the above-mentioned precursor liquid into the autoclave and seal it, then put the autoclave into a furnace set at 140°C in advance, take out the autoclave after reacting for 12 hours, and let it cool naturally.
