Summary: | The invention relates to a method for preparing a super-hydrophobic nano Ni3S2 coating on the surface of a nickel mesh. The method comprises the following steps taht firstly, pretreating the surface of the nickel mesh to remove oil stains and impurities attached to the surface of the nickel mesh; dissolving a proper amount of sodium hydroxide and ammonium persulfate into deionized water, fully stirring and uniformly mixing, soaking the nickel mesh in the solution and heating in a water bath at the temperature of 35-65 DEG c, so that an oxidation layer is formed on the surface of the nickel net, taking out the sample, washing with deionized water and rapidly drying; then preparing a water solution with a certain concentration of sodium sulfate decahydrate and ammonium fluoride, fully stirring and heating to 60-90 DEG c, soaking the nickel mesh subjected to the treatment in the solution, and keeping the temperature for a certain time to obtain a Ni3S2 coating with a nano-protrusion structure; finally, the super |
