纤维素的功能材料

纤维素是地球上最为丰富的可再生资源，既可收获又能再生，而且具有价廉，可降解性和对生态环境不产生污染等优点，因而，自本世纪70年代以来，纤维素功能材料的研制与开发一直保持向上发展的良好趋势，并在多数工业化国家实现工业化，本文着重介绍自80年代以来纤维素，纤维素衍生物以及木质纤维素的功能材料，诸如吸水，吸油，吸重金属离子和特种物质的吸附材料；热塑性与液化木质纤维素材料，以及生物活性材料之新近进展。

Functional Cellulosics

Cellulose is an old polymer with manynew industrial applications.The research anddevelopment of functional materials derived fromcellulose,cellulose derivatives and lignocellulosics iscurrently one of the most active areas in the newmaterial science because of their availability,relatively low cost and readiness to be transformedinto a great variety of important materials.Recently,many of fuctional cellulosics have been created and/or commercialized in most of the industrializedcountries.The present review will deal with themost recent developments is functional cellulosics inwhich super water-absorbent,oil absorbent,and heavy metal absorbent cellulosics; thermoplasticand liguefied lignocellulosics as well as bioactivecellulosics are involved.
