Abstract
A tissue adhesive membrane and a preparation method thereof are provided. The tissue adhesive membrane includes a supramolecular polymer and an enhancer; the supramolecular polymer is prepared by copolymerization of lipoic acid and a biocompatible stabilizer; and the enhancer includes at least one selected from the group consisting of a cationic compound, a cationic polymer, and a metal particle. The tissue adhesive membrane of the present invention can achieve rapid adhesion, seal wounds continuously and effectively, and maintain long-lasting mechanical strength. The components of the tissue adhesive membrane come from natural components of animals and plants, have good biocompatibility, and possess the functions of antibacterial and inhibiting inflammation. The tissue adhesive membrane of the present invention is a hydrophobic adhesive membrane where hydrogen bonding and high surface energy can provide strong adhesion energy and no adverse active groups that may cause irritation or discomfort are contained.
