Embodiment 1
[0057] Process the smooth surface copper sheet into an oriented nanoporous copper sheet material in which half is nanoporous and the other half remains in its original state
[0058] 1), take a smooth surface 2cm 2 The copper sheet was ultrasonically cleaned in acetone for 15 minutes, then ultrasonically cleaned in alcohol for 15 minutes, and finally dried with nitrogen;
[0059] 2), the surface of the smooth copper sheet cleaned in step 1) is subjected to orientation treatment, and the left half or right half of the copper sheet is coated with polyurethane and allowed to cure;
[0060] 3), the copper sheet after the orientation treatment is placed in potassium hydroxide solution, and the copper sheet is connected to the working electrode, the platinum sheet is used as the counter electrode, and the calomel reference electrode is used as a reference. Copper sheet is subjected to cyclic voltammetry treatment, and the two high and low potentials of cyclic voltammetry are respec...
Embodiment 2
[0065] Process smooth copper sheet into nanoporous copper sheet with uniform surface
[0066] 1), take a smooth surface 2cm 2 The copper sheet was ultrasonically cleaned in acetone for 15 minutes, then ultrasonically cleaned in alcohol for 15 minutes, and finally dried with nitrogen;
[0067] 2), the copper sheet after cleaning is placed in sodium hydroxide solution, and this copper sheet is connected on the working electrode, with platinum sheet as counter electrode, with calomel reference electrode as reference, to this copper sheet Carry out cyclic voltammetry treatment, the two high and low potentials of cyclic voltammetry are respectively the reduction potential and oxidation potential of the copper in alkaline solution, so 20 oxidation-reduction cycles are processed;
[0068] 3), the copper sheet treated in step 2) is first repeatedly cleaned with deionized water, and then repeatedly soaked and cleaned with alcohol for three times;
[0069] 4), place the copper sheet a...
Embodiment 3
[0071] The copper wire with a smooth surface is treated to make half of it nanoporous and the other half to maintain the original state of the oriented nanoporous copper wire material
[0072] 1) Take a 2cm long copper wire with a smooth surface and ultrasonically clean it in acetone for 15 minutes, then put it in alcohol and ultrasonically clean it for 15 minutes, and finally dry it with nitrogen;
[0073] 2), the surface of the smooth copper wire cleaned in step 1) is subjected to orientation treatment, and the upper or lower half of the copper wire is coated with polyurethane and allowed to cure;
[0074] 3), the copper wire after the orientation treatment is placed in potassium hydroxide solution, and the copper wire is connected to the working electrode, the platinum sheet is used as the counter electrode, and the calomel reference electrode is used as the reference. Copper wire is subjected to cyclic voltammetry treatment, and the two high and low potentials of cyclic vo...
