Embodiment 1
[0039] A method for preparing an efficient water-collecting self-cleaning superamphiphobic coating, the preparation process of which is as follows:
[0040] (1) Super amphiphobic topcoat preparation: 1 volume part of nano silica sol, 2 volume parts of 28 wt.% ammonia water, 6 volume parts of deionized water, 0.1 volume part of tetraethyl orthosilicate, 0.1 volume part of hydrophobic treatment agent Disperse in 60 parts by volume of absolute ethanol, and continuously mechanically stir at 100 rpm for 12 h to obtain a super amphiphobic topcoat, and the hydrophobic treatment agent is fluorosilane.
[0041] (2) Preparation of resin-coated particles: Select particles to be coated with a particle size of 3 μm. In this example, the particles to be coated are silicon carbide, and the shape of the silicon carbide particles is a conical structure with a bottom diameter of 5-50 μm , the angle at the top is 4-20°, and the particles are dispersed in absolute ethanol under the state of 100 r...

[0046] A method for preparing an efficient water-collecting self-cleaning superamphiphobic coating, the preparation process of which is as follows:
[0047] (1) Super amphiphobic topcoat preparation: 1 volume part of nano silica sol, 2 volume parts of 25 wt.% ammonia water, 6 volume parts of deionized water, 0.1 volume part of tetraethyl orthosilicate, 0.1 volume part of hydrophobic treatment agent Dispersed in 60 parts by volume of absolute ethanol, the hydrophobic treatment agent is fluorosilane, mechanically stirred at 100 rpm for 12 h to obtain a super amphiphobic topcoat;
[0048] (2) Polymer-coated particles: Select the particles to be coated with a particle size of 3-50 μm. In this example, the particles to be coated are molybdenum disulfide, and the shape of the particles is a three-dimensional triangular columnar structure. Disperse the particles in absolute ethanol to obtain a 0.3% mass ratio concentration solution, and then add a hydrophilic polymer to wrap the part...
