Synthesis of biodegradable carboxymethyl cellulose film-loaded magnesium nanoparticles

In this study, carboxymethyl cellulose (CMC) was synthesized from sugarcane bagasse using a pretreatment process, and then a hydrogel containing magnesium oxide nanoparticles (MgO-NPs) was synthesized in situ method. After the preparation of the hydrogel, the supernatant was employed to make the biodegradable nanocomposite film. Ultravoilet-Vis spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), and Fourier 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 (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 (CMC-2) demonstrated a slower rate of biodegradation than the film without nanoparticles (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.
