Enhanced structural, optical, electrical properties and antibacterial activity of PEO/CMC doped ZnO nanorods for energy storage and food packaging applications

The zinc oxide nanorods (ZnONRs) have been successfully prepared via sol–gel way. A series of Poly(ethylene oxide) and Carboxymethyl cellulose (PEO/CMC) blend samples filled with different concentration ZnONRs were using casting method. Transmission electron microscopic (TEM) image showed that the synthesized ZnONPs had a diameter in range 29.29 to 59.09 nm. These characterized by analytical techniques. On basis results obtained from XRD FT-IR analysis, blends are miscible. Fourier transform infrared (FT-IR) spectroscopy exhibited complexation between PEO/CMC ZnONRs. optical energy gap was calculated UV/vis. data. maximum value AC conductivity for pure 1.98 × 10–7 S.cm−1, raising filling increased 3.26 10–6 S.cm−1 at highest concentration. After added ZnONRs, an improvement dielectric constant (ε′) loss (ɛ") detected. can be employment semiconductor industries portable electrochemical batteries, electric vehicles grid storage, due noticed enhancements optical, conductivity. PEO/CMC/ZnONRs films screened their vitro antibacterial activity against S. aureus E. coli bacteria tested. excellent antimicrobial these provides novel simple way synthesis nanocomposites as functional biomaterials has possibility usage food packaging applications.
