| Abstract: | Porous chitosan membranes were prepared using dibutyl phthalate as porogen. The surface structure and the cross section of the porous chitosan membranes were examined by SEM,while water adsorption, water vapor permeation, mechanical property, biodegradation and biocompatibility of the porous chitosan membranes were examined. It shows that the porous chitosan membranes possessed controlled pore sizes, bigger porosity and specific surface area. The biggest water adsorption, porosity and specific surface area were 196%, 71.5% and 1.0472m~2/g, respectively. The porous chitosan membranes possessed better biocompatibility and mechanical strength, the maximal tensile strength is 273.17MN/m~2. |
