纤维素纳米晶体是一种独特的纳米材料，来源于最丰富和几乎取之不尽的天然聚合物纤维素。这些纳米材料由于其机械、光学、化学和流变学性质而受到极大的关注。主要从天然存在的纤维素纤维获得的纤维素纳米晶体在性质上是可生物降解和可再生的，因此它们作为可持续和环境友好的材料用于大多数应用。这些纳米晶体本质上基本上是亲水的;然而，它们可以被表面官能化以满足各种具有挑战性的要求，例如使用疏水聚合物基质开发高性能纳米复合材料。考虑到越来越多的跨学科的研究正在进行的纤维素纳米晶体，这篇评论的目的是整理有关的来源，化学结构，物理和化学分离程序，以及描述的机械，光学和流变性能，纤维素纳米晶体的知识。在不同领域的创新应用，如生物医学工程，材料科学，电子，催化等，其中这些纤维素纳米晶体可以使用，突出显示。
Cellulose nanocrystals are unique nanomaterials derived from the most abundant and almost inexhaustible natural polymer, cellulose. These nanomaterials have received significant interest due to their mechanical, optical, chemical, and rheological properties. Cellulose nanocrystals primarily obtained from naturally occurring cellulose fibers are biodegradable and renewable in nature and hence they serve as a sustainable and environmentally friendly material for most applications. These nanocrystals are basically hydrophilic in nature; however, they can be surface functionalized to meet various challenging requirements, such as the development of high-performance nanocomposites, using hydrophobic polymer matrices. Considering the ever-increasing interdisciplinary research being carried out on cellulose nanocrystals, this review aims to collate the knowledge available about the sources, chemical structure, and physical and chemical isolation procedures, as well as describes the mechanical, optical, and rheological properties, of cellulose nanocrystals. Innovative applications in diverse fields such as biomedical engineering, material sciences, electronics, catalysis, etc, wherein these cellulose nanocrystals can be used, are highlighted.
