Zusammenfassung:The preparation method comprises the following steps: (1) adding polyethylene glycol diacrylate, 1-vinyl-3-butylimidazolium bromide, disulfiram and azodiisobutyronitrile into an organic solvent, carrying out ultrasonic dissolution to obtain a mixed solution, and heating the mixed solution to obtain hyperbranched polyionic liquid HPBIL; (2) the silver ammonia solution and the lignin solution are mixed for a reaction, and then silver-lignin nano particles Ag-Lignin NPs are obtained; and (3) dissolving the lipoic acid, the HPBIL and the Ag-Lignin NPs in an organic solvent, and carrying out high-temperature polymerization, so as to obtain the polylipoic acid-hyperbranched ionic liquid-silver-lignin nanoparticle photo-thermal patch PLA-HPBIL-Ag-Lignin NPs. The invention also provides the polylipoic acid photo-thermal wound patch prepared according to the method and application of the polylipoic acid photo-thermal wound patch in preparation of skin wound antibacterial and repairing products. The lipoic acid photo-t
