Abstract

Nanocrystalline Cellulose (NCC) was prepared by dissolution of Microcrystalline Cellulose (MCC) using Ionic Liquid: !-butyl-3-methylimidazoliurn hydrogen sulfate (BMIM HS04) at dissolution temperatures of 70 °C, 80 °C, and 90 °C, and dissolution time of 30 minutes and I hour respectively. Morphological properties of NCC and MCC were examined using Field Electron Scanning Electron Microscope (FESEM). Chemical characterization of NCC was performed for the analysis of crystallinity CXc) using X-ray Diffraction (XRD) and to analyze the bonds that are present in NCC and MCC using Fourier Transform Infrared Spectroscopy (FTIR). FTIR was also used to analyze the chemical bonds in unused BMIM HS04 and regenerated BMIM HS04. Reduction of MCC particle size by BMIM HS04 dissolution was clearly observed from FESEM images. The crystallinity of NCC obtained through dissolution of MCC in BMIM HS04 showed a significant increase due to the degradation of amorphous region in cellulose. Both MCC and NCC have the same chemical bonds. Chemical bonds in regenerated BMIM HS04 were unchanged, indicating that BMIM HS04 can be recycled and reused.
