Properties of Chitosan Liquid Crystalline Solution

LI Lan-ying,HU Cui-hua,LIU Xiao-li,WANG Li-yan,LIU Jian(Engineering and Technical College of Chengdu University of Technology,Leshan 614007,Sichuan,China)  
Chitosan liquid crystalline(LC) solution were prepared,and the texture and viscosity and order-disorder transformation of chitosan were studied by polarizing optical microscopy(POM) and rheometry and differential scanning calorimetry(DSC)respectively.The results show that the chitosan LC pre-sent fingerprint-like texture,the changes of viscosity with the concentration and stress are similiar to LC polymer solution,and endothermic peaks and exothermic peaks are present in the heating and cooling curves respectively.
