The fabrication of Cellulose nanocrystals (CNCs) from sugarcane baggasse (SCB) using acid hydrolysis at various concentrations (5, 10, 20, 25, and 30%) and ultrasound-assisted is presented in this paper. The fabricated CNCs were also thoroughly analyzed using Fourier Transform Infrared Spectroscopy (FTIR) to investigate surface functional groups and X-ray diffraction (XRD) to investigate structural properties. The particle size distribution following the ultrasonication procedure was also measured using a particle size analyzer (PSA) in this investigation. The content of hemicellulose and lignin will decrease as the concentration of HCl in the hydrolysis process increase. On the other hand, the α-cellulose content was increasing. The best concentration of HCl is 20%. FTIR data shows that a sharper increase in intensity can be seen in the HCl 10% and HCl 20% samples. XRD data revealed that the crystal size was 2.732 nm and the index crystallinity of CNCs was 63,57%, while PSA analysis revealed that the average particle size was 125.1 nm. |
