Face wax is jointly caused.Thereafter Jiang Lei et al. analyses in depth lotus leaf surface micrometer structure, discovery lotus leaf surface cream
There is also nanostructure, this micron and the simultaneous micro-nano structures of nanostructure to be only and cause lotus leaf surface " from clearly on prominent
It is clean " basic reason.The presence of a large amount of micro-nano structures, so that being contacted on the downside of drop with a large amount of gap (air), such as Fig. 1 institute
Show, Surface Tension of Liquid Drops is greatly played, so that surface super hydrophobic effect is presented at spherical shape in drop.
There are many techniques to process simulation superhydrophobic surface structure in the prior art, such as has steam induction phase separation
Method, stencil methods, Electrospinning Method, sol-gal process, template-based extrusion method, laser and plasma etching method, pulling method, etch
Deng in the above-mentioned methods, only laser ablation method is relatively environment-friendly mode, and it is dirty that other modes all have a large amount of industry
Dye seems incompatible under the big themes of the times of current environmental protection.
As described in prior art CN201510284815.1, surface sintering processes are done to alloy surface using laser,
Then cooperate other process flows, can just obtain similar superhydrophobic surface structure, but surface texture obtained by the technology is
It is random；And the technology has the following disadvantages, laser ablation speed is slow, and laser ablation effect is low, and expensive equipment is at high cost,
It is limited etc. to obtain super hydrophobic surface product.
