纤维素／壳聚糖复合材料的制备与应用研究进展

摘要

纤维素／壳聚糖复合材料利用纤维素提高了共混材料的力学性能，同时保持了壳聚糖优良的生物相容性和抗菌性，无毒无污染。但是二者分子内和分子间含有大量的氢键，使得在水和常规有机溶剂中很难溶解，限制了复合材料的加工和应用，离子液体的出现为二者的溶解和复合提供了新的思路。综述了纤维素／壳聚糖复合材料的制备方法、制备体系及在工业吸附、生物医疗、食品包装和纺织工业领域的应用，重点介绍了离子液体在此复合材料制备过程中的应用，以为纤维素／壳聚糖复合材料的制备工艺和应用发展提供参考。%The cellulose/chitosan composite can improve the mechanical properties of the blend material due to the cellulose,while maintains the good biocompatibility and antimicrobial properties of chitosan.The composite are non-toxic and pollution-free.However,cellulose and chitosan are difficult to dissolve in water and conventional orga-nic solvents,because of its large proportion of intramolecular and intermolecular hydrogen bonds,which strictly limit its processing and applications.The presence of the ionic liquid provides a new approach for the composite.This re-view aims to summarize the preparation method,preparation system of cellulose/chitosan composite materials and its application in industrial adsorption,biomedical,food packaging and textile industry,with emphasis on the application of ionic liquid in the fabrication of the composite.This paper is expected to provide a reference for the development of fabrication and application of cellulose/chitosan composite.
