Abstract

The invention belongs to the field of super-amphiphobic materials, and particularly relates to a fluorine-containing anti-fingerprint oil polymer and preparation thereof, and application of the polymer in the field of super-amphiphobic materials. The preparation method comprises the following steps: carrying out reaction on perfluoropolyether acyl fluorine and a reactant A to obtain a double-bond-containing perfluoropolyether monomer; carrying out copolymerization on the double-bond-containing perfluoropolyether monomer and a silane monomer to obtain the fluorine-containing anti-fingerprint oil polymer, wherein the structures of the perfluoropolyether acyl fluorine and silane monomer are respectively disclosed as Formula I and Formula II. The fluorine-containing anti-fingerprint oil polymer contains siloxy groups, and thus, the copolymer can be bonded with the matrix surface by utilizing the siloxy-hydroxy coupling characteristic, thereby constituting the super-amphiphobic surface. The super-amphiphobic surface prepared from the fluorine-containing polymer has the advantages of high bonding firmness with glass and friction resistance, and is suitable for industrial production and application.

Description

technical field [0001] The invention belongs to the field of super-amphiphobic materials, and in particular relates to a fluorine-containing anti-fingerprint oil polymer and its preparation and application in the field of super-amphiphobic materials. Background technique [0002] With the development of the electronic industry, the application of touch screen is more and more extensive, from mobile phone, iPad, to ATM, industrial control equipment and display screen and TV. Due to the convenience and speed of the touch screen, we often leave fingerprints and oil stains on the surface of the touch screen during use. At the same time, it is not easy to clean, which will affect the normal use of the screen. Therefore, it has become the direction of many researchers to study and prepare a super amphiphobic anti-fingerprint oil that is waterproof, oil-proof and wear-resistant. [0003] The C-F bond contained in the organic fluorine material has a large bond energy and a short bo...
