摘　　要：纳米纤维素具有较高的物理机械强度、独特的光学与电学和磁力学性能和流变性能、蕴含量丰富、与环境友好等特点,近几年,已成为全球林产品研究和材料科学界研究的热点。本文主要介绍了纳米纤维素的机械制备方法,即高压均质化、微射流、精细研磨、冷冻粉碎;还介绍了预处理技术,即碱预处理、TEMPO氧化预处理和酶预处理;最后介绍了国外的一些有关纳米纤维素的合作研究项目。Nanocellulose （NC） is a natural nanoparticle that is extracted from cellulose, the most abundant natural polymer in the world. NC has unique strength, optical, electrical and magnetic properties and is bio-compatible. These unusual and versatile properties can be used to create a wide variety of new products. The mechanical preparation methods of nanocellulose, that is, high-pressure homogenization, microfluidizer, micro- grinding, crushing in frost were introduced. The pre-treatment techniques including alkaline pre-treatment, TEMPO oxidation pre-treatment and enzymatic pre-treatment were also introduced. Finally some collaborative research projects on nanocellulose in North American, Europe and Japan were overviewed.
