The invention discloses a method for obtaining an anti-platelet activation function by a polyurethane material. The method comprises the following steps: coating baicalein with bovine serum albumin to obtain baicalein nanoparticles; mixing baicalein nano-particles and a dopamine solution, and carrying out surface grafting reaction on medical polyurethane; and fully washing and drying the modified medical polyurethane material to obtain a finished product. The method of the invention fully utilizes the characteristic that the baicalein is easy to dissolve in the ethanol solution, and simultaneously adopts a bovine serum albumin coating method to keep the activity of the baicalein. The method has simple process, reaction conditions are easy to protect the activity of the traditional Chinese medicine, the process is easy to amplify, and large-scale production is realized. |
