Synthesis of magnesium oxide nanocomposite film made from sugarcane bagasse waste

Abstract

Abstract In this study, hydrogels comprised of magnesium oxide nanoparticles (MgO-NPs) are synthesized in situ and employed to make films from biopolymer nanocomposite materials. Synthesis of CMC from various types of wastes mainly depends on the whole pre-treatment process. UV-Vis spectroscopy, Fourier transmission electron microscopy (FTIR), scanning electron microscopy (SEM), Energy dispersive X-ray (EDX), and transform infrared spectroscopy were used to characterize MgO-NPs. A TEM image reveals MgO-NPs of 100 nm embedded in the sugarcane bagasse carboxymethyl cellulose (SB-CMC) hydrogel network. The successful absorption peak at 295 nm, which is brought on by the surface plasmon resonance (SPR), indicates the existence of MgO-NPs. A film with nanoparticles (SB-CMC-2) demonstrated a slower rate of biodegradation than the Film without nanoparticles (SB-CMC-1) sample. Glycerol typically increases film flexibility and extension. Film tensile strength (TS) and opacity are increased by MgO-NPs in CMC film while moisture content, solubility, and elongation at break are decreased.
