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.
本论文的主要创新点:(1)以NaOH水溶液/无水乙醇为凝固液,采用溶液纺丝法制备出保水性壳聚糖/聚乙烯醇纤维,共混和戊二醛交联极大提高了壳聚糖纤维力学性能;(2)用壳聚糖和明胶共混,以溶液纺丝法制备出可控降解的壳聚糖/明胶纤维,并大幅度提高了壳聚糖共混纤维的干、湿态抗张强度;(3)确立了不同取代度N-酰基壳聚糖的合成方法及其膜的结构与性能的关系;(4)利用纤维素新溶剂6%NaOH/4%尿素制备出抗凝血性纤维素/甲壳素共混膜;(5)利用上述纤维素新溶剂制备出抗菌性纤维素/羧甲基壳聚糖共混膜,揭示了羧甲基壳聚糖取代度与抗菌性能的关系;(6)制备出可控降解壳聚糖交联膜。
