Elaboration of a nanomaterial from microcrystalline cellulose and a hydrotalcite Mg2AlCO3) [Elaboration d'un nanomatériau à partir d'une cellulose microcristalline et d'une hydrotalcite Mg2AlCO3]

The development of nanomaterials is recent and require a large multidisciplinary. also,the production process and valorization of properties of these new materials are still emerging. the objective of this work is to synthetize a nano-biomaterial by introducing synthetic clay (hydrotalcite ht) as nanofiller in a natural polymer matrix (microcrystalline cellulose mcc) previously dissolved in naoh and urea solution,using the method of heating by microwaves. differents percentage of hydrotalcite (2,5 and 10%) has been tested. the prepared materials were characterized by ir spectroscopy,xrd and dta/tga. 2% of hydrotalcite is proved to be the optimum charge rate for obtaining a nanomaterial.
