Preparation of cellulose nanoparticle from cinnamon

Abstract

The preparation of cellulose nanostructures is considered in this paper. Cellulose nanoparticles<br />(nano cellulose) were extracted from cinnamon for the first time. The chemically-induced<br />destruction strategy based on controlled strong acid hydrolysis treatment was used for dissolution<br />of lignin and fragmentation of cellulose to nano sized structure. The products were<br />characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transform<br />infrared (FT-IR), UV-Vis and Mass spectroscopy. SEM images demonstrated the cellulose<br />nanoparticles production. Size distribution histogram which was obtained from the SEM image<br />showed that nanoparticles size were less than 100 nm with average size about 50 nm. XRD<br />analysis showed amorphous structure of nanoparticles. Chemical structures and functional<br />group of cellulose nanoparticles approved using FT-IR. UV-VIS spectrum of macro cellulose,<br />micro cellulose and nano cellulose were done in water, acetone and acetic acid. These spectrums<br />illustrate the same absorption for tree materials in agues, organic and acidic solvents<br />approving the stability of structures and maintaining molecular structure during making nano<br />cellulose. Mass spectroscopy peaks are in good agreement with the structure of the cellulose<br />and its fragmentation during analysis.
