TEMPO mediated synthesis of Nanocellulose from Terminalia Elliptica

. Madhuri R, Virupaxappa S Betageri, Onkarappa H S and Latha M S


In the current work, a natural residue Terminalia Ellipticais processed into cellulose by pre-treating it with NaOH (5%) & NaClO2 (5%). Further, the cellulose has been converted to nanocellulose through the acid hydrolysis method followed by ultra sonication. The Crystallinity and functional group analysis was studied using X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR), respectively. The surface morphological investigation of prepared nanocellulose was carried out using scanning electron microscope (SEM) transmission electron microscope (TEM). The thermal stability was investigated using thermogravimetric and derivative thermal analysis (TGA/DTA). The obtained results revealed semicrystallinity nature, good thermal stability, and fibrous nanocellulose nature with agglomeration.
