This present work reports the synthesis of Cellulose nanocrystals (CNCs) from cotton using an ultrasound-assisted acid hydrolysis. Further, the synthesized CNCs was comprehensively characterized using Fourier Transform Infrared Spectroscopy (FTIR) to analyze surface functional groups and X-ray diffraction (XRD) in studying structural characteristics. Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA) have been used to study the thermal properties of CNCs. Morphology of CNCs was studied using a Transmission Electron Microscope (TEM) and Scanning Electron Microscope (SEM). The crystallite size was found to be 10-50 nm using XRD data and the average particle size to be 221 nm using PSD analysis.
本工作报道了使用超声辅助酸水解从棉花中合成纤维素纳米晶体（CNC）。此外，通过傅里叶变换红外光谱（FTIR）分析表面官能团和 X 射线衍射（XRD）研究结构特性，对合成的 CNC 进行了全面表征。差示热分析（DTA）和热重分析（TGA）用于研究 CNCs 的热性能。使用透射电子显微镜（TEM）和扫描电子显微镜（SEM）研究 CNCs 的形态。通过 XRD 数据发现晶粒尺寸为 10-50nm，通过 PSD 分析发现平均粒径为 221nm。
