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 continuous expansion of cellulose applications, modification and modification of functionalized materials by Atom Transfer Radical Polymerization (ATRP) are the hot topics in the current research. The reaction system evolved from the traditional heterogeneous system to a homogeneous system, and cellulose substrates were gradually transformed from cellulose derivatives to natural cellulose. This review summarizes the recent progress and achievements of cellulose graft modification. According to different types of cellulose derivatives, natural cellulose, respectively, according to different dissolution systems were described graft modification process, focusing on the special properties of graft copolymers and its application in different fields, and its prospects were predicted And outlook.
