木质材料制备的微/纳纤丝具有生物可降解、高强度、导热低等诸多优点,是一种环境友好型材料。本文简单介绍了普通法制备微/纳纤丝的特点,同时具体介绍了酶处理法制备微/纳纤丝的国内外研究进展。从木质纤维素中分离的微/纳纤丝添加到聚合物中后,聚合物的强度、热稳定性等性质会得到显著提高。 Micro / nanofibers made from wood-based materials have many advantages such as biodegradability, high strength and low thermal conductivity, and are environmentally friendly materials. This article briefly introduced the common law preparation of micro / nanofibrils characteristics, at the same time specifically introduced the enzymatic treatment of micro / nanofibers research progress at home and abroad. After the micro / nanofibres separated from lignocellulose are added to the polymer, the properties such as strength and thermal stability of the polymer are significantly improved.
