Preparation method and application of amphiphilic fluorine-containing nano-microsphere/fluorine-containing epoxy resin hybrid

Abstract

Disclosed are a preparation method for and applications of an amphiphilic fluorine-containing nanosphere / fluorine-containing epoxy resin hybrid. The preparation method comprises the following steps: microspheres are dispersed in solvent B, an epoxy resin and catalyst D are added, reacted under thermal insulation, solvent B is removed, then vacuumed and dried, acquired is a hybrid of the microspheres having grafted at the surface thereof an epoxy group and of the epoxy resin; the acquired product is dissolved in solvent E, then a hydrophilic compound and catalyst D1 are added, when reacted, a fluorine-containing compound and catalyst D2 are added for a reaction, solvent E is concentrated when the reaction is completed, and finally, water is added while continuously stirring to acquire the fluorine-containing nanosphere / fluorine-containing epoxy resin hybrid. The epoxy group in the amphiphilic fluorine-containing nanosphere / fluorine-containing epoxy resin hybrid prepared per the present invention allows for implementation of firm bonding among the fluorine-containing microspheres and between same and a substrate via chemical bonds, is feasible for most substrates, and provides universality. The method of the present invention is simple and feasible and implementation of mass production is expected.

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.
