چکیده مقاله :
The preparation of cellulose nanostructures is considered in this paper. Cellulose nanoparticles(nano cellulose) were extracted from cinnamon for the first time. The chemically-induceddestruction strategy based on controlled strong acid hydrolysis treatment was used for dissolutionof lignin and fragmentation of cellulose to nano sized structure. The products werecharacterized by scanning electron microscope (SEM), X-ray diffraction (XRD), Fourier transforminfrared (FT-IR), UV-Vis and Mass spectroscopy. SEM images demonstrated the cellulosenanoparticles production. Size distribution histogram which was obtained from the SEM imageshowed that nanoparticles size were less than 100 nm with average size about 50 nm. XRDanalysis showed amorphous structure of nanoparticles. Chemical structures and functionalgroup of cellulose nanoparticles approved using FT-IR. UV-VIS spectrum of macro cellulose,micro cellulose and nano cellulose were done in water, acetone and acetic acid. These spectrumsillustrate the same absorption for tree materials in agues, organic and acidic solventsapproving the stability of structures and maintaining molecular structure during making nanocellulose. Mass spectroscopy peaks are in good agreement with the structure of the celluloseand its fragmentation during analysis.
