abstract

Objective of this work was to compare morphology, crystalline and thermal properties of cellulose nano fibers derived from wheat straw by two different processes (ball milling and acid hydrolysis treatment). The characterization of extracted CNFs was done by Scanning electron micrograph (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Thermogravimetric analysis (TGA). It was found from morphological, crystalline and thermal analyses that isolated cellulose nanofibers have diameter of nano meter ranges (10–25 nm), 68–80 % crystallinity and decomposition temperature of around 284–353° C, depending upon isolation techniques.
