Abstract:
The objective of the study was to explore the utilization of residual Rose stems as a source of cellulose nanofibers (CNFs). The CNFs were obtained by a so-called conventional method and another one proposed in this study. They were characterized by Fourier-Transform Infrared spectroscopy (FTIR), X-ray diffraction, scanning, and transmission electron microscopy (SEM, TEM). Changes in FTIR spectra indicate that conventional treatment adequately removed hemicellulose and lignin from the surface of the fibers. The degree of crystallinity of CNFs was 56.2%. The peaks observed in X-ray diffraction patterns refer to the presence of Type I cellulose. Results are promising for taking advantage of agricultural residues for the isolation of CNFs and their application in polymer matrices as reinforcement material.
