The specific properties of materials, such as the palate adhesion, dynamic cruor, anti-bacterial and the degradability of lysozyme, were studied, which provide valuable data for further application. The main creative ideas are listed as follows:(1) The water-retention chitosan/poly vinyl alcohol blend fiber was obtained by coagulating in 10％ NaOH/ethanol solution, and the blend and crosslink due to GA can enhance the mechanical properties of fiber;(2) The controlled degradable chitosan/gelatin blend fiber was obtained by solution filature, and the mechanical properties were improved;(3) The N-acylchitosan with the different degree of substitution were successfully prepared, and the relationship between structure and properties was estabilished;(4) By a new solvent system of 6％ NaOH/4％ urea for cellulose, the blood anti-coagulant function films were prepared by blending cellulose with chitin;(5) In the same solvent system above mentioned, the anti-bacterial blend films based on cellulose and carboxymethyl-chitosan were prepared, and the relationship of DS and the anti-bacterial property was concluded;(6) The controlled degradable chitosan films was obtained by the chemical crosslink.
