摘要：

In this study, we performed preparation and characterizations of the chitin/cellulose composite gels and films using the two ionic liquids, 1-allyl-3-methylimidazolium bromide and 1-butyl-3-methylimidazolium chloride. First, chitin and cellulose were dissolved in each appropriate ionic liquid. Then, the two liquids were mixed in the desired ratios at 100 degrees C to give the homogeneous mixtures. The gels were obtained by standing the mixtures for 4 days. On the other hand, the films were obtained by casting the mixtures on glass plates, followed by soaking in water and drying. The obtained gels and films were characterized by XRD and TGA measurements. The mechanical properties of the gels and films were evaluated under compressive and tensile modes, respectively.
