title: Preparation and properties of photo-crosslinkable hydrogel based on photopolymerizable chitosan derivative.
abstract: Photopolymerizable chitosan derivative was synthesized by chitosan and methyl acroloyl glycine (MAG). The chemical structures and physical properties were characterized by FT-IR, (1)H NMR, XRD and TGA. The thermal stability of chitosan derivative was lower than chitosan. The chitosan derivative was amorphous compared with the high degree crystallization of chitosan. The hydrogels were prepared based on chitosan derivative via photopolymerization with different concentrations of photoinitiator 2959. The surface of hydrogel showed porous network and the pore size distribution tended to become homogeneous with the increase of the concentration of 2959, while the swelling property decreased due to more crosslinking.
