Hydrogel materials have many excellent properties and a wide range of applications. Recently, a new type of hydrogel has emerged: cellulose nanofiber (CNF)-based hydrogels, which have three-dimensional nanofiber networks and unique physical properties. Because CNFs are abundant, renewable, and biodegradable, they are green and eco-friendly nanoscale building blocks. In addition, CNF-based hydrogel materials exhibit excellent mechanical properties and designable functions by different preparation methods and structure designs, demonstrating huge development potential. In this Perspective, we summarize the recent progress in the development of CNF-based hydrogels and introduce their applications in elastic hydrogels, ionic conduction, water purification, and biomedicine, highlighting future trends and opportunities for the further development of CNF-based hydrogels as emerging materials systems.
水凝胶材料具有许多优异的性能和广泛的应用。最近，出现了一种新型水凝胶：基于纤维素纳米纤维（CNF）的水凝胶，它具有三维纳米纤维网络和独特的物理性能。由于CNF丰富、可再生且可生物降解，它们是绿色环保的纳米级构建单元。此外，基于CNF的水凝胶材料通过不同的制备方法和结构设计展现出优异的机械性能和可设计的功能，显示出巨大的发展潜力。在这篇综述中，我们总结了基于CNF的水凝胶开发的最新进展，并介绍了它们在弹性水凝胶、离子传导、水净化和生物医学方面的应用，突出了基于CNF的水凝胶作为新兴材料系统进一步发展的未来趋势和机遇。
