Synthesis of Nano-Cellulose from Okra Fibre and FTIR as Well as Morphological Studies on It

Nano-cellulose was extracted from Okra fiber by various chemical treatment such as alkali treatment, bleaching and then by acid hydrolysis. The final products were characterized by means of Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). FTIR results showed that the hemicelluloses and lignin were removed from the extracted nano-cellulose. On the other hand, SEM analysis showed that the surface morphology of raw fiber, bleached fiber, alkali treated fiber and nano-cellulosic fiber. The surface of raw fiber was rough, not plain and smooth but the surface of Crystalline Nano Cellolose (CNC) became plain, smooth and not rough for the removing of lignin and fatty and waxy materials from it and simultaneously there is a honey comb structure appeared which will be very helpful for producing nano composites with polymeric materials. Size of the okra fiber was cellulose reduced into nano-sized particles.
