| Abstract: | Adoption of wet molding technology and different proportion chitosan/regenerated cellulose fiber composites were prepared by directly blending chitosan powder and cellulose in l-butyl,3-methylimidazolium chloride ionic liquid at room temperature.The morphology,structure and other property of the fibers were characterized by Fourier transform infrared spectrum(FT-IR),scanning electron microscope(SEM) and so on.The result shows that the mechanical properties,degree of orientation,crystallization and breaking strength are reduced with the increase of chitosan content in fiber composites.Cellulose fiber and chitosan can achieve a good micro-scale mixing while ionic liquid as co-solvent.The ionic liquid can eventually be completely dissolved from the material. |
