The Synthesis and Characteristic of PAA-Ch/Sio2 Hydrogel Nanocomposites by Radiation Methods for Bone Materials

摘要：

　　Generally,hydrogel compounds derived from either natural or synthetic chemical suffer from lack of mechanical strength.So high strength poly(acrylic acid)-chitosan-silica (PAA-Ch-Si)hydrogels were prepared by UV light or γ-ray irradiation method for scaffold material application in this paper.The absorption peaks from FTIR show the evidence for the successful grafting of PAA-Ch-Si hydrogel material through radiation co-polymerization.The mechanical property analysis indicate that the maximum compressive strength of this hydrogel was significantly increased to ~42 MPa when PAA incorporated with both chitosan and nano-silica.And from the test results,we can observe that these nanocomposites are fitted to appling for biomedical materials.
