对人类活动对环境的影响的广泛关注导致人们希望用天然衍生的替代品取代人工功能材料。因此，多糖作为一种可再生的、可生物降解的和生物相容性的功能性纳米材料的原料而受到越来越多的关注。特别是，纤维素和几丁质的纳米晶体已经成为多种应用的通用和可持续的构建块，从机械加固到结构着色。这种兴趣很大程度上源于这些胶体稳定的纳米颗粒在水中自组织成溶性胆甾液晶的倾向，这种液晶可以很容易地根据其周期性、结构和几何形状进行操作。重要的是，这种螺旋有序可以保留在固态中，为复杂的纳米结构薄膜、涂层和颗粒提供了一条可接近的途径。本文综述了纤维素纳米晶体悬浮液形成彩虹色结构彩色薄膜的过程，并探讨了该过程中每个阶段的化学和物理现象的机制。然后与几丁质纳米晶体（chnc）进行类比，允许对关键差异进行批判性评估，并提出结构着色策略。重要的是，总结了将该技术从学术界转化为工业的进展，并提出了未解决的科学和技术问题，作为对社区的挑战。
Widespread concerns over the impact of human activity on the environment have resulted in a desire to replace artificial functional materials with naturally derived alternatives. As such, polysaccharides are drawing increasing attention due to offering a renewable, biodegradable, and biocompatible feedstock for functional nanomaterials. In particular, nanocrystals of cellulose and chitin have emerged as versatile and sustainable building blocks for diverse applications, ranging from mechanical reinforcement to structural coloration. Much of this interest arises from the tendency of these colloidally stable nanoparticles to self-organize in water into a lyotropic cholesteric liquid crystal, which can be readily manipulated in terms of its periodicity, structure, and geometry. Importantly, this helicoidal ordering can be retained into the solid-state, offering an accessible route to complex nanostructured films, coatings, and particles. In this review, the process of forming iridescent, structurally colored films from suspensions of cellulose nanocrystals (CNCs) is summarized and the mechanisms underlying the chemical and physical phenomena at each stage in the process explored. Analogy is then drawn with chitin nanocrystals (ChNCs), allowing for key differences to be critically assessed and strategies toward structural coloration to be presented. Importantly, the progress toward translating this technology from academia to industry is summarized, with unresolved scientific and technical questions put forward as challenges to the community.
