纤维素纳米晶体（Cellulose nanocrystals，CNCs）是一种广泛存在于自然界中的棒状纳米颗粒，由于其高强度、高结晶度、高比表面积、低密度、生物降解性和低毒性等优点，近年来在研究和工业上引起了极大的兴趣。CNC可以容易地从天然纤维素源中提取，并且广泛地用于例如聚合物增强、造纸和流变改性。CNC表面上的高密度官能团允许各种化学表面改性，这允许在宽范围内调节CNC的性质。这篇综述简要概述了CNCs的表面化学改性，特别是那些经常用于我们自己的研究，重点放在一些最突出的领域的利益CNCs，特别是聚合物增强，可愈合的聚合物，刺激响应的纳米杂化材料，皮克林乳液稳定剂，病毒抑制剂，液晶组装。
Cellulose nanocrystals (CNCs) are rod-like nano-scale particles that are widely available in nature and have recently gained great interest in both research and industry, due to their high strength, high crystallinity, high surface area, low density, biodegradability and low toxicity. CNCs can be easily extracted from natural cellulose sources and are broadly useful, for example in polymer reinforcement, paper manufacturing, and rheology modification. The high density of functional groups on the surface of CNCs allows various chemical surface modifications, which permit tuning the properties of CNCs over a wide range. This review gives a brief overview of surface chemical modification of CNCs, focusing especially on those often utilized for our own research, which focuses on some of the most prominent areas of interests of CNCs, notably polymer reinforcement, healable polymers, stimuli-responsive nanohybrids, Pickering emulsion stabilizers, viral inhibitors, and cholesteric liquid crystal assemblies.
