  • Abstract Abstract
    In this study, the different molecular weights of chitosan were prepared by adding concentrate hydrochloric acid. The membranes were prepared by different molecular weights of chitosan blend with different composition of cellulose. The interaction of polymer molecules and the mechanical properties of the membranes were investigated by FTIR、SEM and DMA. And the membranes antimicrobial property was examined by shake-flask method. The optimum condition of characteristics assessment of the membranes preparation will be used in future wet spinning research. FTIR spectroscopy results indicated that the functional groups were not changed by blending. SEM shows that the membrane has smooth surface and tough cross section structure. DMA results show that the mechanical properties would not affected by the molecular weights of chitosan but were highly affected by the content of cellulose. Meanwhile, we found that when the content of chitosan more than cellulose, the membrane has a better antimicrobial property. We also found that optimum condition for the membrane preparation is chitosan/cellulose equal 1.
