| description | The invention relates to a method for modifying a hydrogel hydrophilic coating on the surface of a material. The method comprises the following steps: step 1, material surface treatment; 2, modifying the surface of the material treated in the step 1 with a polymer containing initiation activity and a silane coupling agent structure, and then performing ultrasonic treatment; 3, a hydrogel monomer solution is used for reacting with the surface of the material treated in the step 2, so that a hydrophilic monomer in the hydrogel monomer solution and the surface of the material treated in the step 2 form covalent bond linkage, and the hydrogel hydrophilic coating is obtained on the surface of the material. Compared with the prior art, the preparation method is simple and easy to operate, the hydrogel hydrophilic coating is uniform and controllable in thickness, and oxygen isolation is not needed. The hydrogel hydrophilic coating prepared by the preparation method disclosed by the invention has good hydrophilicity |
