The present invention discloses a plant polyphenol modified polymer membrane as well as a preparation method and application thereof, in particular relates to the field of modified polymer membranes with anti-fouling properties. In the prior art, due to low surface energy of the polymer membrane, the polymer membrane is susceptible to contamination with proteins, oils and the like and causes a series of temporary or permanent pollution problems. The polymer membrane provided by the invention utilizes the super-strong adhesive ability of plant polyphenols and the coordination of polyphenols andmetal ions to build a hydrophilic coating on the surface of a hydrophobic polymer membrane. The polymer membrane provided by the invention has the advantages of simplicity, high efficiency, mild reaction condition and strong practicability. The controllable hydrophilic modification of a hydrophobic polymer can be realized by changing the conditions of the dip-coating time, the concentration of aplant polyphenol mixed solution, the pH, the temperature and the like, and a high permeation flux can be maintained in the course of cross-flow continuous work, so that the polymer membrane has a verygood application prospect in the field of water treatment.
