摘要
纳米纤维素纤维在水溶液中可以通过物理缠绕以及氢键结合的方式形成具有稳定三维网络结构的水凝胶。纳米纤维素水凝胶具有无毒性及良好的生物相容性,在生命科学领域应用前景广阔。而纳米纤维素气凝胶保持凝胶的三维网络结构,其高比表面积、低密度及优异的隔热性能等在建筑、能源电子器件、油水分离等领域也同样有着巨大的应用潜力。本文从纳米纤维素基本特性、纳米纤维素水凝胶、纳米纤维气凝胶研究及应用情况进行了介绍,并分别对纳米纤维素水凝胶与气凝胶的优异性能及应用进展进行了总结。
Nanocellulose hydrogel with stable three-dimensional (3D) network can be formed m aqueous nanocellulose fibre suspensions through mechanical entanglement and intermolecular hydrogen bonds. It shows prosperous applications in the field of life-science due to its nontoxicity and biocompatibility. The nanocellulose aerogel with reserved 3D network from hydrogel, exhibiting high specific surface area, low density and excellent heat-insulating property, reveals great potential applications in the areas of building, energy storage and electronic devices, and water/oil separation. This review assembles the current knowledge on the basic properties of nanocellulose and overviews the application ofnanocellulose hydrogel and aerogel with respective properties.
