Abstract

The invention discloses a metal-modified superhydrophobic material and a preparation method thereof, belongs to the field of preparation of superhydrophobic materials, and aims to solve the technical problems in environmentally-friendly, energy-saving and efficient preparation of the superhydrophobic material. The preparation method comprises the following steps: S1, preparing conical nano nickel by using a polylactic acid template; S2, impregnating the conical nano nickel in a gold ion-containing gold plating solution for replacement reaction; S3, carrying out cleaning and drying; S4, then impregnating the conical nano nickel in a hexadecyl mercaptan solution for complex reaction; S5, carrying out cleaning and drying, thus obtaining the metal-modified superhydrophobic material, wherein the metal-modified superhydrophobic material is sulfydryl-carried metal gold, and hill-shaped bulges are formed on the surface of the metal-modified superhydrophobic material. The metal-modified superhydrophobic material is prepared according to the preparation method; the metal-modified superhydrophobic material is the sulfydryl-carried metal gold, and the hill-shaped bulges are formed on the surface of the metal-modified superhydrophobic material.

Description

technical field [0001] The invention relates to the field of preparation of superhydrophobic materials, in particular to a metal-modified superhydrophobic material and a preparation method thereof. Background technique [0002] Hydrophobic materials have broad application prospects in both scientific research and daily life. The hydrophobic effect mainly relies on two aspects: the material has a hydrophobic microscopic morphology and the surface contains hydrophobic substances or groups. Due to the good super-hydrophobic function on the surface of the lotus leaf, the water falling on the lotus leaf will form water droplets due to the surface tension and slide down. Observed under a high electron microscope, the leaf surface of the lotus leaf is covered with "small bags" one by one. If water droplets fall on the contact points of the "small bags", it will achieve a hydrophobic effect. At the same time, coating low surface energy substances on the surface of materials is als...
