Cellulose was extracted from sugar palm fibres (Arenga pinnata) by conducting delignification and mercerization treatments. Subsequently, sugar palm nanocrystalline celluloses (SPNCCs) were isolated from the extracted cellulose with 60 wt% concentrated sulphuric acid. The chemical composition of sugar palm fibres were determined at different stages of treatment. Structural analysis was carried out by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Morphological analysis of extracted cellulose and isolated nanocrystalline cellulose (NCCs) was investigated by using field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), and transmission electron microscopy (TEM). The thermal stability of sugar palm fibres at different stages of treatment was investigated by thermogravimetric analysis (TGA). The results showed that lignin and hemicellulose were removed from the extracted cellulose through the delignification and mercerization process, respectively. The isolated SPNCCs were found to have length and diameters of 130 ± 30 nm and 9 ± 1.96 nm, respectively.

通过进行脱木素和丝光处理，从糖棕纤维（Arenga pinnata）中提取纤维素。随后，从提取的纤维素中分离出糖棕纳米晶纤维素（SPNCC），其中60 wt％浓硫酸。在不同的治疗阶段确定糖棕榈纤维的化学组成。结构分析通过Brunauer-Emmett-Teller（BET），X射线衍射（XRD）和傅里叶变换红外光谱（FT-IR）进行。使用场发射扫描电子显微镜（FESEM），原子力显微镜（AFM）和透射电子显微镜（TEM）对提取的纤维素和分离的纳米晶纤维素（NCC）的形态进行了研究。通过热重分析（TGA）研究了糖棕榈纤维在不同处理阶段的热稳定性。结果表明，分别通过脱木素化和丝光处理过程从提取的纤维素中去除了木质素和半纤维素。 分别为±  30  nm和9  ±  1.96  nm。
