Embodiment Construction

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0047] Room temperature curing polymer materials are widely used in navigation, aerospace, pipeline transportation and many other fields, such as radar and aircraft casings, ships, submarine cabins, etc., and they also have important uses in daily life . According to the current literature, there is no simple and practical method for preparing various types of water, aqueous solutions, and various oils that are super-repellent at the same time. The superphobic polymer surface is a very important practical preparatio...

Abstract

The invention provides a super-amphiphobic polymer film layer and a manufacturing method thereof. The method includes the steps of: providing a template, the template includes a surface, the surface has a first micro-nano structure; forming an auxiliary layer on the surface of the template; A polymer film layer is formed on the surface of one side, wherein the polymer film layer replicates the first micro-nanostructure of the surface of the template through the auxiliary layer, so that the polymer film layer forms the same structure as the first micro-nano structure. The second micro-nanostructure with the nanostructure reversed; performing a release treatment to separate the auxiliary layer, the polymer film layer from the template to obtain a composite film layer of the auxiliary layer and the polymer film layer; And removing the auxiliary layer in the composite film layer to obtain the polymer film layer, wherein the polymer film layer has super-hydrophobic and super-oleophobic properties.

Description

【Technical field】 [0001] The invention relates to a superamphiphobic polymer material and a manufacturing method thereof. 【Background technique】 [0002] Surface wettability is an important property of solid surfaces and is mainly determined by two factors of the solid surface: surface chemical composition and microstructure. Superphobic coatings have many potential applications, such as: liquid transmission, liquid power systems, anti-coloring, outdoor anti-pollution materials and micro-liquid equipment, etc., which have extensive and important uses. In recent years, the preparation of superhydrophobic surfaces and superoleophobic surfaces It has attracted more and more attention, and more and more literatures have reported such surfaces with special wetting properties prepared by different methods. However, it turns out that fabricating superoleophobic surfaces with contact angles greater than 150° and contact angle hysteresis less than 10° is much more difficult than fab...
