In this work, cellulose microcrystal has been isolated from Apocynum venetum (AV) through acid hydrolysis. In addition, the properties of microcrystalline cellulose (MCC-N) extracted from AV are compared with those of commercially available microcrystalline cellulose (MCC-C). The characterizations of MCCs are studied by X-ray diffraction, Fourier transforms infrared spectroscopy, scanning electron microscopy, thermo gravimetric analyzer, and Zeta potential. As compared to MCC-C, MCC-N unveil more crystallinity percentage, fewer impurities, and comparable thermal stability without modifying the chemical composition of the sample. Besides, SEM images demonstrate rough surface and slight aggregation of extracted MCC from AV. Extracted MCC from AV can be possibly utilized as a reinforcement in green composites or hydrophilic micro composites as well as a source for AV fibre derived nanocellulose. Moreover, MCC-N can also be used in food, cosmetics, and medical industries.

罗布麻微晶纤维素的提取与表征

在这项工作中,纤维素微晶已通过酸水解从罗布麻 (AV) 中分离出来。此外,将从 AV 中提取的微晶纤维素 (MCC-N) 的特性与市售微晶纤维素 (MCC-C) 的特性进行比较。MCC 的表征通过 X 射线衍射、傅里叶变换红外光谱、扫描电子显微镜、热重分析仪和 Zeta 电位进行研究。与 MCC-C 相比,MCC-N 显示出更高的结晶度百分比、更少的杂质和相当的热稳定性,而不会改变样品的化学成分。此外,SEM 图像表明从 AV 中提取的 MCC 表面粗糙和轻微聚集。从 AV 中提取的 MCC 可能用作绿色复合材料或亲水性微复合材料的增强材料,以及 AV 纤维衍生的纳米纤维素的来源。此外,MCC-N还可用于食品、化妆品和医疗行业。
