Embodiment 1

[0026] In this embodiment, an orthotropic wettability magnetron flexible surface material is prepared according to the following steps:

[0027] (1) Spray 4 layers of release agent on the surface of a glass petri dish (Φ80mm), and let it dry for later use.

[0028] (2) Weigh 2g of silane coupling agent KH570, 9.8g of methanol and 88.2g of deionized water in a beaker, adjust the pH value of the mixed solution to between 4 and 5 with glacial acetic acid, then add 200g of iron powder, and use a high-speed mixer Thoroughly stir for 30 minutes, and finally dry and grind in a vacuum oven to obtain carbonyl iron powder.

[0029] (3) Mix 18.0 g of component A and 1.8 g of component B of PDMS uniformly to obtain a PDMS solution; add silicone oil to the PDMS solution and stir evenly to obtain a mixed solution, and the volume fraction of silicone oil in the mixed solution is 5%;

[0030] Carbonyl iron powder was added into the mixed solution (the mass ratio of carbonyl iron powder to PD...

Abstract

The invention discloses a preparation method of an orthotropic wettability magnetron flexible surface material. After mixing PDMS and carbonyl iron powder to remove air bubbles and pouring it into a mold, it is first put into an oven to solidify to a semi-solidified state. , and then put it into a uniform magnetic field to cure completely. The magnetically controlled flexible surface material obtained by the present invention has different rolling angles in different directions, and its wettability is anisotropic, and has good application prospects in the aspects of droplet directional transportation, droplet screening and the like.

Description

technical field [0001] The invention belongs to the technical field of intelligent materials, and in particular relates to a preparation method of an orthotropic wettability magnetron flexible surface material. Background technique [0002] The preparation methods of superhydrophobic materials include mechanical processing, etching, template method, sol-gel method, self-assembly method, deposition method, electrostatic particle adsorption method, microemulsion method and one-step method. However, these methods have problems such as high requirements for experimental equipment and complicated operation. The preparation of superhydrophobic materials by using a magnetic field to construct a surface microstructure can effectively avoid the above problems. The magnetron superhydrophobic material constructed by using a magnetic field has the advantages of fast response speed and stable properties. [0003] The preparation method of the existing magnetron superhydrophobic materia...
