Abstract

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 with 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 for 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 agree well with the structure of the cellulose and its fragmentation during analysis.
