Nanocellulose of hemp fibers was obtained by employing the chemo‐mechanical technique, which included three stages of chemical treatments followed by mechanical grinding. Morphological analysis of untreated, treated, and nanocellulose of hemp fibers was performed by field emission scanning electron microscopy. Further, the crystalline behavior of these fibers was also measured by X‐ray diffraction and observed a higher crystallinity (80.95%) for the nanocellulose. Furthermore, change in chemical structure of fibers after chemical treatments and mechanical grinding was analyzed by Fourier transform infrared spectroscopy, and elimination of hemicelluloses and lignin was confirmed. Higher thermal stability of nanocellulose was confirmed by thermogravimetric analysis and differential scanning calorimetry analysis. The antibacterial analysis was also performed using Escherichia coli (E. coli) and bacillus bacteria. An excellent antibacterial property was offered by the isolated nanocellulose, which makes it a suitable reinforcement to be used in polymeric films and composites for the packaging applications.

化学法从大麻纤维中分离纳米纤维素及其表征

大麻纤维的纳米纤维素是通过化学机械技术获得的，该技术包括三个阶段的化学处理，然后进行机械研磨。通过场发射扫描电子显微镜对未处理的，处理过的和纳米纤维素纤维进行形态分析。此外，还通过X射线衍射测量了这些纤维的结晶行为，发现纳米纤维素具有更高的结晶度（80.95％）。此外，通过傅立叶变换红外光谱分析了化学处理和机械研磨后纤维的化学结构变化，并确认消除了半纤维素和木质素。通过热重分析和差示扫描量热分析确认了纳米纤维素的更高的热稳定性。大肠杆菌（E. coli）和芽孢杆菌属细菌。分离出的纳米纤维素具有出色的抗菌性能，使其成为用于包装应用的聚合物薄膜和复合材料的合适增强材料。
