Most of hydrogels derived from either natural or synthetic sources suffer from lack of mechanical strength.In this study, high strength poly(acrylic acid)-chitosan silica (PAA-Ch-Si) hydrogels were prepared by UV polymerization for tissue engineering application.The characteristic absorption peaks from FTIR provide evidence for the successful preparation of PAA-Ch-Si hydrogel through UV polymerization.
