Solid state nuclear magnetic resonance (ssNMR) is a powerful and attractive characterization method for obtaining insights into the chemical structure and dynamics of a wide range of materials. Current interest in cellulose-based materials, as sustainable and renewable natural polymer products, requires deep investigation and analysis of the chemical structure, molecular packing, end chain motion, functional modification, and solvent-matrix interactions, which strongly dictate the final product properties and tailor their end applications. In comparison to other spectroscopic techniques, on an atomic level, ssNMR is considered more advanced, especially in the structural analysis of cellulose-based materials; however, due to a dearth in the availability of a broad range of pulse sequences, and time consuming experiments, its capabilities are underestimated. This critical review article presents the comprehensive and up-to-date work done using ssNMR, including the most advanced NMR strategies used to overcome and resolve the structural difficulties present in different types of cellulose-based materials.
固态核磁共振（ssNMR）是一种强大且有吸引力的表征方法，可用于深入了解各种材料的化学结构和动力学。目前对纤维素基材料作为可持续和可再生天然聚合物产品的关注，需要对其化学结构、分子堆积、端链运动、功能改性以及溶剂 - 基质相互作用进行深入研究和分析，这些因素强烈决定了最终产品的性能并定制其终端应用。与其他光谱技术相比，在原子水平上，ssNMR被认为更为先进，尤其是在纤维素基材料的结构分析方面；然而，由于缺乏广泛的脉冲序列以及实验耗时，其能力被低估。这篇批判性综述文章展示了使用ssNMR所做的全面且最新的工作，包括用于克服和解决不同类型纤维素基材料中存在的结构难题的最先进NMR策略。
