摘要
随着纤维素应用领域的不断扩大,通过原子转移自由基聚合(Atom Transfer Radical Polymerization,ATRP)对其进行修饰改性并获得功能材料是当前研究的热点。反应体系从传统的非均相体系发展到均相体系,纤维素基材也从纤维素衍生物逐步转变为天然纤维素。本文主要综述了纤维素接枝改性的最新研究进展和成果。纤维素衍生物根据不同类别,天然纤维素则依据不同溶解体系分别描述了接枝改性的过程,重点介绍接枝共聚物的特殊性能及其在不同领域的应用,并对其前景进行了预测及展望。
With the expansion of the cellulose application field, ATRP process by modifying cellulose and obtaining functional materials is a hotspot of current research. Changing reaction system from traditional heterogeneous system to homogeneous system, cellulose base material is gradually transformed into natural cellulose from cellulose deriva- tives. This paper summarizes the latest progress of cellulose, including different cellulose derivatives and natural cellulose, graft modification and results, describes the process of properties of the graft copolymer and its application in different grafting modification. With emphasis on the special fields, its prospect is forecasted.
