The invention discloses a hydrogel material and a preparation method and application thereof. Wherein, the two preparation raw materials of acrylic anhydride modified collagen and polyethylene glycol diacrylate are combined and matched to realize performance complementation; specifically, the hydrogel material can be endowed with biological activity by inducing acrylic anhydride to modify collagen in the polyethylene glycol diacrylate, and the existence of the polyethylene glycol diacrylate can overcome the defect of insufficient mechanical property when the collagen is used alone; and the modified collagen can be formed by ultraviolet crosslinking and curing, the forming process is simple, the three-dimensional structure is not limited, and the application range is wide. Through the mode, the hydrogel material disclosed by the invention has excellent mechanical properties and biological activity. |
