The objective of this study was to determine the effect of delignification on the properties of bamboo cellulose nanofibers and its nanocomposites. Milled bamboo powder (150-200 mesh) was delignified with sodium chlorite-acetic acid (SC-AA) treatment in reactions 1, 2, 3, and 4 cycles. The delignified bamboo fibers were then fibrillated using wet disk mill (Supermasscolloider MKCA6-2, Masuko Sangyo, Japan). The morphology, functional groups, and crystalline properties of the fibrillation products were characterized. Bamboo cellulose nanofibers and polyvinyl alcohol (PVA) matrix were used to prepare nanocomposites. The physical, optical, and mechanical properties of the nanocomposite were evaluated. The results showed that lignin content of ampel bamboo decreased 12% to 83% after SC-AA delignification. The diameter of ampel bamboo cellulose nanofibers decreased with increasing delignification. The Fourier Transform Infra-Red (FTIR) spectra confirmed that there was a decrease in lignin content although there were still residues left on the cellulose nanofibers. The crystallinity and atomic size of the crystals decreased with increasing delignification reaction. The water absorption and solubility of nanocomposites decreased with increasing delignification reaction on ampel bamboo. Ampel bamboo cellulose nanofibers with 4 times delignification had the highest nanocomposite transparency. Nanocomposite strength increased with increasing delignification.
