Evaluation of physical, mechanical and biological properties of Te2O3/Cr2O3/Pr6O11 embedded in polyvinyl alcohol nanocomposite
This study presents a novel polyvinyl alcohol (PVA)-based nanocomposite enriched with Te2O3, Cr2O3, and Pr6O11 oxides, aimed at enhancing optical properties and antibacterial efficacy for biomedical and optoelectronic applications. Structural analysis through FT-IR, XRD, and XPS confirmed successful integration of the oxides into the PVA matrix. The nanocomposite exhibited a notable reducing in the optical band gap from 3.35 eV (PVA) to 2.75 eV (PVA-Te2O3-Cr2O3-Pr6O11), indicating improved crystalline ordering. Dielectric analysis revealed stability across frequencies, with a refractive index increase from 2.0 (pure PVA) to 2.38 (PVA-Te2O3-Cr2O3-Pr6O11), highlighting potential for electronic applications. Furthermore, the PVA-Te2O3-Cr2O3-Pr6O11 composite exhibited strong antibacterial activity, with inhibition zones of 15.5 ± 0.4 mm against E. coli and 14.2 ± 0.4 mm against S. aureus, outperforming other tested compositions. These findings suggest that this nanocomposite could be effectively utilized in biomedical devices and optoelectronics.
期刊介绍：
Launched in January 1998, Inorganic Chemistry Communications is an international journal dedicated to the rapid publication of short communications in the major areas of inorganic, organometallic and supramolecular chemistry. Topics include synthetic and reaction chemistry, kinetics and mechanisms of reactions, bioinorganic chemistry, photochemistry and the use of metal and organometallic compounds in stoichiometric and catalytic synthesis or organic compounds.
