Facile synthesis and application of aluminum oxide nanoparticle based biodegradable film

Abstract

This study focuses on the synthesis of aluminum oxide nanoparticles (AlO-NPs) hydrogel through in situ method and formation of biopolymer nanocomposite film. UV-Vis spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy (TEM), particle size analyzer, and energy dispersive X-ray spectrum were performed for the characterization of AlO-NPs. TEM micrograph demonstrates the presence of AlO-NPs in the range of 50-100 nm in the hydrogel network made from sugarcane bagasse carbo-xymethyl cellulose (SB-CMC) and synthetic carboxymethyl cellulose (CMC). The successful absorptions peak at 210 nm while conducting UV-Vis spectroscopy suggests existence of AlO-NPs. The antibacterial properties of AlO-NPs were analyzed using the disc plate diffusion technique against Gram-negative bacteria:Escherichia coli (ATCC 433); and Gram-positive bacteria: Bacillus subtilis (ATCC 1688). AlO-NPs present in CMCs films reduce moisture content, solubility; elongation at break and increases films' tensile strength.

Synthesis of magnesium oxide nanocomposite film made from sugarcane bagasse waste

“…The resulting mixture was next placed in a hot water bath set at 85 ºC for two hours. The generated CMC adhesive was collected, rinsed in water to remove the remaining NaOH and ECH, and then nally dried at 65 ºC in an oven [40].…”

“…An effective basic substance like NaOH oxidizes Mg 2+ ions in MgO-NPs. In the synthesis of nanoparticles, this method is straightforward and affordable [40].…”

“…The band is allocated to the C-H (aliphatic) at (2910 to 2970 cm − 1 ) respectively. Stretching of the -OH group is connected to the large absorption band at (3300 to 3400 cm − 1 ) [40].…”

“…MgO-NPs with an increase in DS and a magnesium chloride content of 0.03 M are more aggregate in nature. EDX quantitative testing encloses the nanostructure that has been created during the in situ process, which is made up of about 75.64 wt% Mg, 18.02 wt% oxygen, and 6.34 wt% carbon for SB-CMC [40].…”

“…Because it is a polyelectrolyte, CMC has recently received a lot of scienti c attention. With applications across numerous industries, it is currently the most popular cellulose ether [37][38][39][40][41][42][43][44][45]. For use as a component in detergents, adhesives, pesticides, lubricants, cloth, cement, ceramics, oil drilling mud, and the coating and paper industries, large amounts are produced in crude marketable grades, exclusive of any re ning [46].…”
