| titleOfInvention | Antibacterial and anti-adhesion medical polypropylene patch with multi-layer surface structure and preparation method and use thereof |
| abstract | The invention provides an antibacterial and anti-adhesion medical polypropylene patch with a multi-layer surface structure, a preparation method and application thereof, and belongs to the technical field of biomedical materials. The polypropylene patch is a polypropylene patch whose surface is simultaneously grafted with oxidized dextran and ε-polylysine. Since the surface of the polypropylene patch of the present invention is modified with ε-polylysine and oxidized dextran, it has a synergistic effect on broad-spectrum antibacterial and prevention of postoperative adhesion. At the same time, the patch also has excellent tissue compliance and tissue compatibility. In addition, the ε-polylysine and oxidized dextran used for the surface modification of polypropylene are covalently grafted, so the modified layer is very stable in structure. The raw materials used for the preparation of the patch are all approved by the CFDA, which also ensures the safety of the patch when it is used, and has a good application prospect. |
