摘要：

This work presents a new way to prepare and isolate nanometric cellulose fbrils as extracted from Citrullus Colocynthis (Cc) seeds. The nanofbrils were then characterized using spectroscopic, thermal and morphological/structural techniques.IR-Raman spectra of cellulose fbers confrmed that the treatment they went through, efectively removed all non-cellulosic material (i.e. hemicellulose and lignin). In addition to that, TGA results indicated a good and higher thermal stability of the extracted cellulose. HPLC and 1H NMR measurements were carried out to estimate the chemical composition of cellulose from Cc seeds. TEM confrmed the presence of nanofbers in the treated sample; XRD (WAXS-SAXS) data show that the cellulose nanofbers have a higher crystallinity. The preparation (extraction and treatment) of cellulose and cellulose nanofbers from the Cc seeds as well as their thermal, structural and morphological characterizations, were successful.
