Preparation method of amphiphilic fluorine-containing nanoparticle/fluorine-containing epoxy resin hybrid and application thereof

Abstract

The invention discloses a preparation method of an amphiphilic fluorine-containing nanoparticle / fluorine-containing epoxy resin hybrid and an application thereof. The preparation method comprises the following steps: dispersing the nanoparticle in a solvent B; adding epoxy resin and a catalyst D; preserving heat and reacting; removing the solvent B; then vacuum drying to obtain a nanoparticle and epoxy resin hybrid grafted with epoxy groups on the surface; dissolving the obtained product in a solvent E; then, adding a hydrophilic compound and a catalyst D1; after reaction, adding a fluorine-containing compound to be reacted with a catalyst D2; after reaction, concentrating the solvent E; and finally, adding water to keep stirring to obtain the fluorine-containing nanoparticle / fluorine-containing epoxy resin hybrid. According to the epoxy groups in the amphiphilic fluorine-containing nanoparticle / fluorine-containing epoxy resin hybrid prepared by the invention, fluorine-containing nanoparticles as well as the fluorine-containing nanoparticles and a base material thereof can be firmly combined through chemical bonds. The method is feasible to almost base materials, so that the method is universal. The method provided by the invention is simple and feasible, and expected to realize production on a large scale.

Description

technical field [0001] The invention belongs to the field of super amphiphobic materials, and in particular relates to a preparation method and application of an amphiphilic fluorine-containing nano microsphere / fluorine-containing epoxy resin hybrid body. Background technique [0002] Surface wettability is one of the important characteristics of solid surfaces. The wettability can be measured by the contact angle of water on the surface. Usually, the surface with a water contact angle of more than 150° and a rolling angle of less than 10° is called a superhydrophobic surface. With a contact angle of more than 150° to oil, it can be considered as a super oleophobic surface. If the static contact angles of water and oil on a surface are both greater than 150° and the rolling angles are both less than 5°, the interface can be called a superamphiphobic interface. Superhydrophobic surfaces and superamphiphobic surfaces have a certain self-cleaning function, that is, surface pol...

Problems solved by technology

However, the treatment process of this method is cumbersome and requires high reagents and equipment, and the fluorine-containing microspheres need to be dispersed in a fluorine-containing solvent, and there are no adhesive groups on the surface, so the adhesion is not very strong.

[0007] Although the above-mentioned patents solve many problems in superamphiphobic aspects, there are still many problems in the process of large-scale production and implementation, such as complicated methods and high costs.
