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.
由天然材料制备的纳米纤维素在获得各种最终产品的优异材料性能方面具有广阔的前景。在这项研究中，商用天然棉用氢氧化钠水溶液处理以去除半纤维素和木质素，然后收集纤维素。收集的纤维素用硫酸进行酸水解以获得纳米纤维素。通过傅里叶变换红外光谱、X 射线衍射和扫描电子显微镜进一步对制备的纳米纤维素进行了表征，以阐明其化学结构、结晶度和形态。
