由天然材料制备的纳米纤维素具有获得各种最终产品的上级材料性质的有前途的广泛机会。本研究以市售天然棉为原料，采用氢氧化钠水溶液处理，去除半纤维素和木质素，得到纤维素。使用硫酸对收集的纤维素进行酸水解以获得纳米纤维素。利用傅里叶变换红外光谱、X射线衍射和扫描电镜对纳米纤维素的化学结构、结晶度和形貌进行了表征。(C)2017爱思唯尔B.V.保留所有权利。
Nanocellulose prepared from the natural material has a promising wide range of opportunities to obtain the superior material properties towards various end-products. In this research, commercially available natural cotton was treated with aqueous sodium hydroxide solution to eliminate the hemicellulose and lignin, then cellulose was collected. The collected cellulose was subjected to acid hydrolysis using sulfuric acid to obtain nanocellulose. The prepared nanocellulose was further characterized with the aid of Fourier transform infrared spectroscopy, X-ray diffraction and Scanning Electron Microscopy to elucidate the chemical structure, crystallinity and the morphology.
