چکیده

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