This work reports the effect in extraction micro-fibrillated cellulose (MFC) from sorghum bicolor using a graduation treatment of alkalinization and followed by TEMPO-mediated oxidation. The graduation treatment was aimed to defibrillate the natural fiber into microfibrils with a high crystallinity ratio. The obtained MFC was characterized using FTIR-ATR, FE-SEM and XRD to evaluate their chemical composition, morphology and crystallinity index. The FTIR spectra MFC after treatment revealed that lignin and hemicellulose had been removed from fibers and predominant polymorph cellulose type I. The morphological analysis with FE-SEM for MFC after TEMPO-mediated oxidation showed that the fibers were cleaner and more fibrillated into microfibrils with small-scale fibers approximately 10 microns. XRD diffraction showed the highest crystallinity index of 72% for alkalization treatment followed by TEMPO-mediated oxidation.
