Abstract

The invention discloses a polyvinylpyrrolidone-iodine bionic complex polymer and a preparation method thereof. The polyvinylpyrrolidone-iodine bionic complex polymer is prepared from polyvinylpyrrolidone and iodine, wherein the polyvinylpyrrolidone-iodine bionic complex polymer has the structure represented as the specification; the catechol groups in the polyvinylpyrrolidone-iodine bionic complexpolymer provided by the invention and complex iodine on a polyvinylpyrrolidone main chain play a synergistic role, so that the polyvinylpyrrolidone-iodine bionic complex polymer shows excellent adhesion performance and stain resistance to a substrate, is suitable for the surfaces of various substrates, and is durable in antibacterial ability and good in antibacterial stability; according to the preparation method of the polyvinylpyrrolidone-iodine bionic complex polymer, the polyvinylpyrrolidone-iodine bionic complex polymer is obtained by taking the polyvinylpyrrolidone mussel protein polymer as a raw material and complexing the polymer with iodine under the action of a solvent. The preparation process is simple and efficient, reaction raw materials are cheap and easy to obtain, and amplification of the operation process and realization of industrial production are facilitated.

Description

technical field [0001] The invention relates to the technical field of compound synthesis, in particular to a polyvinylpyrrolidone-iodine biomimetic complex polymer and a preparation method thereof. Background technique [0002] The widespread use of biopolymer materials (medical sutures, catheters, etc.) and artificial organs (heart valves, artificial kidneys, etc.) has brought great convenience to clinical treatment. However, long-term or short-term indwelling of polymer materials or artificial organs in the human body has the risk of bacterial infection, which has become one of the main problems facing current medicine. [0003] Based on the mechanism of infection, the study found that the antibacterial treatment of the surface of the implant can effectively prevent the bacterial infection caused by the implant. Because of its strong bactericidal power, good effect, various types, no secondary pollution, stable performance, non-volatile, and no penetration into human or ...
