纤维素及其主要衍生物接枝改性的研究进展

Research Progress of Grafted Modification of Cellulose and its Main Derivatives

纤维素是自然界大量存在的可再生高分子材料,是理想的环境友好材料,但是纤维素本身结构复杂,难溶、难融,使其应用受到限制。利用接枝共聚的方法改性纤维素,使其能部分或完全取代石油基塑料将极具前景。本文综述了近年来纤维素、二醋酸纤维素、乙基纤维素接枝改性的进展,并对今后的研究方向进行了展望。

Cellulose is abundant in nature, which is renewable and friendly to the environment. But it＇s difficult to fusibility and solubility limited the applications of cellulose. Thus, there is tremendous interest in chemical modifications of cellulose and its derivatives by graft copolymerization to improve the performance. It can partially or completely replace petroleum-based plastics in the future. The research progress of Graft Copolymerization of Cellulose, cellulose diacetate, ethyl cellulose in recent years was summarized. The development prospects of this field were also forecasted.
