Abstract

Bamboo leaves represent a promising and sustainable source of cellulose nanofibers, as evidenced by their cellulose content of 37.52%. This study aims to isolate and characterize cellulose nanofibers derived from bamboo leaves using the steam explosion method. X-ray diffraction (XRD) analysis revealed characteristic diffraction peaks at 2θ values of 22.41°, 34.46°, 44.59°, 81.39°, and 98.21°. The crystallinity index of cellulose increased significantly from 11.57% in raw bamboo leaves to 43.60% after the second steam explosion treatment, indicating enhanced structural order. Fourier-transform infrared (FTIR) spectroscopy confirmed the presence of key functional groups, including O–H, C–O, and C–H, verifying the cellulose structure. Scanning electron microscopy (SEM) analysis showed irregular aggregation and heterogeneous fiber morphology. Overall, the results demonstrate the progressive removal of lignin and hemicellulose during each treatment stage, highlighting the effectiveness of the steam explosion method for isolating cellulose nanofibers from bamboo leaves.
