  • Publication number: 20240424172
    Abstract: Disclosed is a method for constructing a hydrophilic, antifouling coating on the surface of a medical implantable material. The method comprises the following steps: 1) pretreating the surface of the medical implantable material to obtain a clean surface and/or a hydrophilic active site; and 2) impregnating the medical implantable material that has been pretreated in step 1) in a precursor solution for reaction so as to obtain a reaction interface layer or a free radical reaction and/or polymerization site on the surface of the medical implantable material; and removing the medical implantable material from the solution: 3) carrying out a polymerization grafting reaction; and 4) after the reaction in step 3) is complete, performing a wash and drying, thus finishing the construction of the hydrophilic, antifouling coating on the surface of the medical implantable material.
