Embodiment 1
[0034] For the preparation method, see figure 1 , this embodiment is a method for preparing an anisotropic superhydrophobic structure, which can effectively reduce the running resistance of the hull, and specifically includes the following steps:
[0035] (1) Put the tip of the surgical blade outward, and stick solder on the other end, and perform welding operation under a microscope by micromachining, so that the tip of the scalpel is closely arranged on the surface of the metal roller to form an array with controllable spacing. A metal rod with a scalpel blade is rolled on the surface of a high-density polyethylene (PE) plate, leaving an array of scalpel blade anti-structures.
[0036] (2) PDMS (polymethylsiloxane) and curing agent are mixed at a volume ratio of 10:1, vacuumed to remove internal air bubbles, and then poured on the surface of the PE template. After a curing time of 3 hours, the template was uncovered to obtain a flexible anisotropic surgical blade structure ...
Embodiment 2
[0046] This embodiment is a method for preparing an anisotropic superhydrophobic structure, which specifically includes the following steps:
[0047] (1) Fix the surgical blade (commercially available) on the three-dimensional platform at an angle of 45 degrees, and control the spacing of each microstructure through the x and y directions of the three-dimensional platform, which can be regulated at 50-500 microns; through z (vertical) Adjust the depth in the direction to adjust the height of the structure, periodically focus on the surface of the PE board, and form a blade anti-structure array on the surface of the PE board.
[0048] (2) PDMS (polymethylsiloxane) and curing agent are mixed at a ratio of 15:1, the internal air bubbles are removed by vacuum, and then poured on the surface of the PE template. After a curing time of 3 hours, the template was uncovered to obtain a flexible anisotropic surgical blade structure on the PDMS substrate.
[0049] (3) The preparation of ...
