Abstract

Over the past few years, cellulose nanocrystals (CNCs), also known as nanocrystalline cellulose (NCCs), have received significant attention owing to their diverse spectrum of applications. CNCs are commonly considered in nanomedicine, the food industry, tissue engineering, energy and storage applications, paper and textile industry, polymeric composites, and bio-catalysis. Due to the versatility of CNCs and CNC-derived materials, there is increasing importance in characterizing their properties using spectroscopic techniques. These spectroscopic techniques include solid-state nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron (XPS) spectroscopy, and Raman spectroscopy. This review focuses on the characterization of CNCs and CNCs-derived materials using the aforementioned spectroscopic techniques. This review also discusses the background, experimental procedures, sample preparation, and spectral analysis methods used in these techniques.

摘要

在过去的几年中，纤维素纳米晶体（CNC），也称为纳米晶纤维素（NCC），由于其广泛的应用而受到广泛关注。CNC 通常被用于纳米医学、食品工业、组织工程、能源和存储应用、造纸和纺织工业、聚合物复合材料和生物-催化。由于 CNC 和 CNC 衍生材料的多功能性，使用光谱技术表征它们的特性越来越重要。这些光谱技术包括固态核磁共振 (NMR) 光谱、傅里叶变换红外 (FTIR) 光谱、X 射线光电子 (XPS) 光谱和拉曼光谱。本综述侧重于使用上述光谱技术表征 CNC 和 CNC 衍生材料。本综述还讨论了这些技术中使用的背景、实验程序、样品制备和光谱分析方法。
