The characteristic of cellulose nanofiber-based (CNF) hydrogel isolated crosslinked with two different agents such as N,N′-methylene bisacrylamide (MBA) and chitosan were investigated for the first time from abaca fiber (Musa textilis). The isolation of α-cellulose from abaca fiber was performed using acid hydrolysis and alkalization, subsequently the cellulose was treated with steam explosion (thermomechanochemical process) to finally obtain CNF. In addition, the CNF hydrogels were characterized to determine the chemical, thermal, structural, and morphological properties using fourier transform infrared spectroscopy (FT-IR), x-ray diffraction (XRD), scanning electron microscope (SEM), tunneling electron microscope (TEM), and thermogravimetry analysis (TGA)/differential thermal analysis (DTA), analysis. FTIR analysis suggests that MBA and chitosan were successfully crosslinked with CNF. Besides, the swelling and crosslinking degree of 3582 and 85% for MBA-CNF and chitosan-CNF of 137 and 90% were achieved. We found that the morphology of chitosan-CNF was rough and coarse as compared to MBA-CNF hydorgels. Accordingly, chitosan-CNF hydrogel not only demonstrated better thermal stability at higher temperature, but also zero irritation index owing to the higher crystallinity index.

首次研究了用蕉麻纤维（Musa textilis）与N，N'-亚甲基双丙烯酰胺（MBA）和壳聚糖等两种不同试剂交联的纤维素纳米纤维基（CNF）水凝胶的特性。）。使用酸水解和碱化作用从蕉麻纤维中分离出α-纤维素，然后用蒸汽爆炸法（热机械化学过程）处理纤维素，最终获得CNF。此外，使用傅里叶变换红外光谱（FT-IR），X射线衍射（XRD），扫描电子显微镜（SEM），隧道电子显微镜（）对CNF水凝胶进行了表征，以确定其化学，热，结构和形态特性TEM）和热重分析（TGA）/差热分析（​​DTA）分析。FTIR分析表明MBA和壳聚糖已成功与CNF交联。另外，MBA-CNF和壳聚糖-CNF的溶胀和交联度为3582和85％，137和90％。我们发现，与MBA-CNF水凝胶相比，壳聚糖-CNF的形态既粗糙又粗糙。因此，壳聚糖-CNF水凝胶不仅在较高温度下表现出更好的热稳定性，而且由于较高的结晶度而显示出零刺激指数。
