| Abstract: |
| Hyaluronic acid methacrylate（HAMA）was synthesized by the reaction of hyaluronic acid sodium salt with methacrylic anhydride at 40 ℃ for 6 h，and then PHAMA was grafted onto the surface of methyl vinyl silicone rubber using ultraviolet radiation.Fourier infrared spectroscopy，scanning electron microscopy and thermogravimetric analysis showed that PHAMA was successfully grafted onto the silicone rubber surface.The surface contact angle of PHAMA grafted silicone rubber decreased from 107.5° to 68.7°，indicating that the hydrophilicity was improved. |
