Beschreibung
Zusammenfassung:	The invention further discloses copper nanoparticle-clove oil double-layer antibacterial hydrogel and a preparation method thereof, the hydrogel is double-layer hydrogel, and the appearance structure, the property and the performance of the double-layer hydrogel are greatly improved. Compared with single-layer CuNPs/PVA and Oil/PVA/PEG hydrogel, the double-layer CuNPs-Oil/PVA/PEG hydrogel has the advantage that the overall antibacterial activity and the mechanical property of the double-layer CuNPs-Oil/PVA/PEG hydrogel are remarkably improved. According to the prepared double-layer CuNPs-Oil/PVA/PEG hydrogel, the upper layer with relatively strong antibacterial ability is in direct contact with the skin, so that the problems of cytotoxicity, biological incompatibility and the like can be solved. And the lower layer is used for promoting growth of epithelial tissues and absorbing wound exudate, has excellent biocompatibility, and promotes wound healing while inhibiting antibacterial growth.
