The invention discloses an ultraviolet-crosslinking fluorine-containing polymer and application thereof in preparing a super-amphiphobic surface. The fluorine-containing polymer is a block polymer or random copolymer polymerized from a monomer A and a monomer B, wherein the polymerization degree of the monomer A is 10-200, and the polymerization degree of the monomer B is 10-500; and the structures of the monomer A and monomer B are respectively disclosed as Formula I and Formula II. The ultraviolet-crosslinking fluorine-containing polymer disclosed by the invention contains azido group, and the azido group can implement crosslinking reaction with most substrates under the ultraviolet irradiation, thereby preparing a super-amphiphobic surface on most substrates. The method for preparing the super-amphiphobic surface is simple, and can be implemented only by catalyzing the ring-opening crosslinking of azide under ultraviolet irradiation, thereby being simple and feasible. The super-amphiphobic surface prepared by the ultraviolet-crosslinking fluorine-containing polymer has the advantages of firm bonding with the substrate, strong binding power, friction resistance and laundering durability. |
