Embodiment 1

[0034] A biomimetic multifunctional anti-ice surface and a preparation method thereof, wherein the biomimetic multifunctional surface includes elastic polyurethane anti-opal film and perfluorinated oil. Such as figure 1 Shown, its preparation method is as follows:

[0035] By using a vertical deposition method, SiO with a size of 200 nm 2 Nanoparticles self-assemble on a glass slide to obtain a colloidal crystal template with an ordered array structure. In order to enhance SiO 2 The close-packed structure of nanoparticles, the glass slide and the fabricated colloidal crystal array were sintered at 400°C in a muffle furnace. Then, carbon black with a characteristic size of 300 nm and a polymer were mixed according to a mass ratio of 5:100 to prepare a polymer solution. Next, the inverse opal structure is formed by filling the polymer solution into the colloidal crystal template and evaporating the solvent to solidify the polymer. After the solvent evaporated completely, hy...

Abstract

The invention relates to a bionic multifunctional ice-resistant surface and a preparation method. The bionic multifunctional ice-resistant surface comprises an elastic inverse opal film and lubricating oil. and According to the bionic multifunctional ice-resistant surface, the lubricating oil with a lubricating effect is sealed in the elastic inverse opal film, with the adsorption of an elastic polymer porous structure and the migration behavior of the lubricating oil combined, the slow release effect of the lubricating oil on the surface of a substrate can be achieved, and the self-lubricating effect is achieved. The preparation method comprises the following steps of: (1) preparing a colloidal crystal template; (2) obtaining a self-supporting elastic inverse opal film; and (3) filling lubricating oil. With the bionic multifunctional ice-resistant surface and the preparation method thereof of the invention, the defect of the single function of ice-resistant surfaces such as a super-hydrophobic surface is overcome; the effects of inhibiting ice nucleation, hindering ice crystal growth and reducing ice adhesion are realized; and a comprehensive multifunctional ice-resistant effect is realized.

Description

technical field [0001] The invention relates to an anti-icing function surface, in particular to a bionic multi-functional anti-icing surface designed to enhance the anti-icing effect, inhibiting the formation of ice nuclei, hindering the growth of ice crystals and reducing the adhesion of ice bodies. Background technique [0002] Functional surfaces for anti-icing or efficient deicing play a vital role in various fields, including infrastructure and energy systems, such as power lines, transportation, energy systems such as spacecraft, cryogenic precision instruments. The life cycle of ice includes three processes: ice nucleation, ice crystal growth, and ice shedding. Correspondingly, there are three ideas for anti-icing: first, inhibit the formation of ice nuclei; water droplets may not freeze even if they are supercooled. An ice crystal, and then extended to grow other ice bodies. Second, hinder ice transfer; third, reduce ice adhesion and accelerate ice shedding. Afte...
