| Abstract: | Calcium algilate/chitosan hydrogel biocomposite is prepared by means of the biomimetic method using SA solution drip into the CaCl2 and CS solution.Then the composite is characterized by means of IR and SEM.The effects of CS molecular weight and concentration on the composite are discussed.The results show that the two phases of SA and CS bond each other strongly. The composite shows highly porous structure and the pores are interconnected.Also many micropores are distributed in the walls of macropores.The ... |
