Tactoids are liquid crystalline microdroplets that spontaneously nucleate from isotropic dispersions, and transform into macroscopic anisotropic phases. These intermediate structures have been found in a range of molecular, polymeric and colloidal liquid crystals. Typically only studied by polarized optical microscopy, these ordered but easily deformable microdroplets are now emerging as interesting components for structural investigations and developing new materials. In this review, we highlight the structure, property and transformation of tactoids in different compositions, but especially cellulose nanocrystals. We have selected references that illustrate the diversity and most exciting developments in tactoid research, while capturing the historical development of this field.This article is part of a discussion meeting issue 'New horizons for cellulose nanotechnology'.
类晶区是从各向同性分散体中自发成核，并转变为宏观各向异性相的液晶微滴。这些中间结构已在一系列分子、聚合物和胶体液晶中被发现。这些有序但易于变形的微滴通常仅通过偏光显微镜进行研究，现在正成为用于结构研究和开发新材料的有趣成分。在这篇综述中，我们重点介绍了不同组成中类晶区的结构、性质和转变，尤其是纤维素纳米晶体。我们选择了一些参考文献，这些文献展示了类晶区研究的多样性和最令人兴奋的进展，同时记录了该领域的历史发展。本文是“纤维素纳米技术的新视野”讨论会议特刊的一部分。
