摘要

纤维素是一种力学性能优异的天然高分子，但难溶不熔的特性限制了其应用范围。在过去的一百多年间，科研工作者一直在持续进行有关纤维素的基础理论和加工方法的研究，已在纤维素绿色溶解体系的构建及溶解机理解析方面获得了长足的进展，但纤维素的热塑加工仍缺少实质性突破。动态热分析是研究纤维素的玻璃转变及次级转变的重要方法，也是揭示纤维素大分子链在不同尺度上运动行为的有效手段，可为实现纤维素的直接热塑加工提供有益的线索。本文简要综述了纤维素的玻璃化行为及其热加工方面的研究进展，旨在为深入理解纤维素的基本运动行为提供更全面的视角，并促进其大规模应用。

Abstract

Cellulose is a natural polymer with excellent mechanical properties

but its application is limited due to the very poor solubility and non-melting characteristics. Over the past 100 years

scientists have been continuously concentrating on the basic theories and processing methods of cellulose

and they have made significant progress in the construction of green cellulose dissolution systems and the analysis of dissolution mechanisms. However

there is still a lack of substantial breakthroughs on the thermoplastic processing of cellulose. The study of dynamic thermal analysis is an important method for investigating the glass transition and secondary transition behaviors of cellulose

and it is also an effective means to reveal the motion behavior of cellulose macromolecular chains at different scales. It can provide useful clues for achieving direct thermoplastic processing of cellulose. In this work

we briefly review the research advance in the glass transition behavior and thermal processing of natural cellulose

aiming to provide a more comprehensive perspective for in-depth understanding of the basic motion behavior of cellulose and to promote its large-scale application.
