Abstract

The invention discloses a water-dispersible crosslinking type fluoropolymer and application of the fluoropolymer in preparation of super-amphiphobic surfaces. The fluoropolymer is a block polymer polymerized by a monomer A and a monomer B and has a molecular weight of 500-47000, wherein the mole ratio of the monomer A to the monomer B is 1: (0.2-10); and the structures of the monomer A and the monomer B are respectively shown in formulas I and II. The fluoropolymer can be used for preparing the super-amphiphobic surfaces. As a crosslinking block part of the water-dispersible crosslinking type fluoropolymer has favorable hydrophilcity, the water-dispersible crosslinking type fluoropolymer can be prepared into an aqueous micelle which takes the fluoropolymer as a core and takes a hydrophilic chain segment as a shell in water, so as to realize the aim of constructing the super-amphiphobic surfaces in a green and environment-friendly water solution. The super-amphiphobic surfaces prepared by using the fluoropolymer are firm in bonding with base materials, rub-resistant and washing-endurable.

Description

technical field

[0001] The invention belongs to the field of super-amphiphobic materials, in particular to a water-dispersible cross-linkable fluoropolymer and its application in preparing super-amphiphobic surfaces. Background technique

[0002] Due to its unique hydrophobic and oleophobic properties, superamphiphobic surfaces can be applied in many aspects of modern industry. For example: superamphiphobic surface has self-cleaning function and can be used for solar panels or some mirrors that need to be kept clean, such as the surface of gas stoves. Furthermore, the formation of a superamphiphobic surface on the metal surface can also greatly improve the corrosion resistance of the metal surface. In addition, if a super-amphiphobic surface is constructed on the wire or high-voltage power grid, it can prevent the wire from forming a frozen layer on the surface of the ice storm or snowstorm, which will cause a short circuit, cause a large-scale power outage, stop production...
