摘要：Tissue engineering basically made up growing the relevant cell in vitro and extracellular matrix. A major goal of tissue engineering is to preparate porous three dimension scaffold for cell proliferate, migrate, differention and to form the structure of desirable tissue and organ. In this study, the effects of various content and macromolecular weight of PEG to chitosan were investigated and evaluated. The pore morphology of chitosan was controlled by changing the concentration and macromolecular weight of PEG.Chitosan porous scaffold has interconecting porosity. The pore morphology can be controlled with varying PEG concentration and macromolecular weight. The pore size is between 10 ～ 50 um, the degree of swelling in water is 85.70%.
