纤维素是一种来源广泛、绿色友好的天然高分子材料。由各种物理化学手段从纤维素中提取出来的纳米纤维素(NC)拥有提取简单、高结晶度和高比表面积等优点,将其用于与其他材料复合时往往能激发出复合材料更大的潜力。基于纳米纤维素表面暴露出的大量羟基结构可以对其进行功能化改性,这对于进一步发挥纳米纤维素的潜力具有重大的意义。简要介绍了纳米纤维素的改性方法以及在电化学储能领域中的应用和展望。
Cellulose is an eco-friendly natural polymer material with a wide range of sources.Nano cellulose (NC) extracted from cellulose by various physical and chemical means has the advantages of simple extraction,high crystallinity and high specific surface area.When used in composites with other materials,it can often stimulate greater potential of composites.Based on a large number of hydroxyl structure exposed on the surface of nanocellulose,functional modification can be carried out,which is of great significance for further developing the potential of nanocellulose.This paper briefly introduced the modification methods of nano cellulose and its application prospect in the field of electrochemical energy storage.
