Preparation method of hernia patch with anti-adhesion and antibacterial functions

The invention belongs to the field of application of biomedical materials, and discloses a preparation method of an anti-adhesion and antibacterial functional hernia patch, which comprises the following steps: firstly, polymerizing a layer of mussel-imitating polydopamine on the surface of polypropylene in situ, and then growing Ag NPs on the surface of the modified polypropylene patch in situ by utilizing the reduction property of the polydopamine to obtain the anti-adhesion and antibacterial functional hernia patch. A polypropylene patch widely used in the market has the problems that infection is prone to occurring, and the polypropylene patch is prone to being adhered to visceral organs, a layer of mussel-imitating polydopamine is polymerized on the surface of polypropylene in situ, the surface adhesion and hydrophilicity of the polypropylene patch can be enhanced by modifying the polypropylene patch with dopamine, and therefore the adhesion phenomenon of the patch is reduced; and silver nanoparticles gro
