Embodiment 1
[0039] Prepare a cuprous sulfide flake array with surface hydrophobicity, the specific steps are as follows:
[0040] (1) Take a copper sheet (produced by Shanghai Sinopharm Group, with a thickness of 0.1 mm and a purity of 99.9%) as a copper-based material, which is polished with sandpaper, ultrasonically cleaned with deionized water, ultrasonically cleaned with absolute ethanol, and then cleaned with deionized water Clean and dry naturally for later use.
[0041] (2) Place the copper-based material treated in step (1) in 2mol L at 15°C -1 React in a sodium hydroxide solution for 48 hours, take it out, wash it with a large amount of deionized water, and dry it naturally.
[0042] (3) Place the treated sample in step 2) in 0.2mol L at 17°C -1 React in a sodium sulfide solution for 24 hours, take it out, rinse it with a large amount of deionized water, and dry it with a hair dryer (the static contact angle of the sample to water in air does not exceed 30°).
[0043] (4) Heat t...

[0046] Prepare a cuprous sulfide flake array with surface hydrophobicity, the specific steps are as follows:
[0047] (1) Get the copper sheet (produced by Shanghai Sinopharm Group, the thickness is 0.1mm, and the purity is 99.9%) to be the copper-based material, polished with sandpaper, ultrasonically cleaned with deionized water, ultrasonically cleaned with absolute ethanol, and cleaned with deionized water, Let it dry naturally.
[0048] (2) Place the copper-based material treated in step (1) in 2mol L at 15°C -1 React in a sodium hydroxide solution for 48 hours, take it out, wash it with a large amount of deionized water, and dry it naturally.
[0049] (3) Place the treated sample in step 2) in 0.4mol·L at 17°C -1 React in a sodium sulfide solution for 72 hours, take it out, rinse it with a large amount of deionized water, and dry it with a hair dryer (the static contact angle of the sample to water in air does not exceed 30°).
[0050] (4) Heat the sample treated in st...
