Effects of CuO nanoparticles on the physical and functional properties of biodegradable polymer‐based composites for biomedical and flexible packaging applications

Journal of Vinyl and Additive Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 22, 2025

Abstract This study explores the development of biodegradable nanocomposites using HPMC, PVA, and CMC, incorporated with copper oxide (CuO) nanoparticles, aiming to create sustainable packaging materials improved antimicrobial properties. CuO nanoparticles were synthesized via a chemical precipitation method integrated into polymer blend through casting technique. X‐ray diffraction (XRD) analysis confirmed monoclinic crystal structure semi‐crystalline nature blends. Fourier transform infrared (FTIR) spectroscopy revealed interactions between host polymers nanoparticles. Optical tests showed that addition reduced both direct (E gd ) indirect gi energy gaps. Electrical conductivity measurements indicated an increase in higher concentrations, attributed enhanced charge carrier mobility crystallinity. Contact angle decreased hydrophobicity as concentration increased, suggesting biocompatibility. Cell viability on HFB4 fibroblast cells demonstrated significant cell viability, highest value observed at 5.0 wt% CuO, indicating favorable biocompatibility for biomedical applications. Moreover, testing inhibition against Gram‐positive Gram‐negative bacteria, stronger effect strains. These results highlight potential enhancing properties HPMC/PVA/CMC blends, offering promising applications materials, electronic devices, fields. Highlights Biodegradable films eco‐friendly use. optical electrical by reducing band Enhanced activity bacteria. Biocompatibility confirmed, showing best performance. Developed are uses packaging.
