摘要
“纳米纤维素的最新制备进展Ⅰ”的续篇Ⅱ,重点阐述了高压均质法、球磨法、微波辅助法、亚临界水解法、双螺杆挤出法等机械法,综合分析了纳米纤维素各种机械制备方法的应用条件和优缺点。其中球磨法结合非极性溶剂可获得亲油晶面暴露的新型纤维素纳米材料,亚临界水解法绿色环保且成本较低,双螺杆挤出法作为一种新的机械处理法相比于传统机械法能耗更低。更进一步地,介绍了纳米纤维素在国内外最新的产业化状况,旨在促进农林纳米纤维素资源的绿色、高效、低成本、可持续开发和高值利用。
This paper is the sequel II of“Recent Preparation Research of Nano-Cellulose I”,focusing on mechanical methods such as high pressure homogenization,ball milling,microwave-assisted method,subcritical water hydrolysis method and twin screw extrusion method.The advantages and shortcomings of mechanical preparation methods of nanocellulose are further analyzed with application conditions.The ball milling method combined with non-polar solvents can obtain new cellulose nanomaterials with exposed lipophilic crystal faces.The subcritical hydrolysis method is green,environmental friendly and lower cost.As a new mechanical treatment method,the twin-screw extrusion method has lower energy consumption compared to traditional mechanical methods.Furthermore,the latest industrialization status of nanocellulose is introduced as well,aiming to promote the green,efficient,low-cost,sustainable development and high-value utilization of agricultural and forestry nanocellulose resources.
