中文摘要: |
作为新兴绿色多功能纳米材料,纳米纤维素在诸多高端领域均具有广泛的应用前景。然而,由于纤维素自身的分子结构特性以及纳米材料大比表面积等原因,纳米纤维素在水相体系中存在着易絮聚、分散性差等问题。为解决上述问题,近年来科研人员从多方面入手进行了诸多研究。本文从纤维素分子结构出发,基于静电排斥和空间位阻两种分散原理,系统综述了提高纳米纤维素在水相体系中稳定分散的研究及进展,并对纳米纤维素在水相体系中稳定分散的方法进行了归纳总结,以期为寻求绿色高效的稳定分散方法提供一定参考。 |
Abstract: |
Nanocellulose has shown a lot of potential as an emerging, green, and multifunctional material in many cutting-edge fields. However, nanocellulose often suffer from the problems such as poor dispersion and prone to aggregation in aqueous solvent, due to its molecular structure and high specific surface area. Recently researchers have exerted a lot of efforts on solving these issues. Based on the electrostatic repulsion and steric hindrance on nanocellulose, the recent research progress on improving the stable dispersion of nanocellulose in aqueous solvent is systematically reviewed in this study. Furthermore, a brief conclusion and outlook on the methods for stabilizing the dispersion of nanocellulose in aqueous solvent is presented in this paper, which provides a guidance for seeking an efficient and environment-friendly approach improving the dispersion of nanocellulose. |
