| Abstract: | In this work, ZnSnO 3 /ZnO/cellulose acetate nanocomposites have been efficiently fabricated by simple wet chemical co-precipitation and drop casting techniques. The study characterized the nanocomposite's microstructure, morphology, dielectric and impedance spectra, dynamic mechanical analyses, and antibacterial performance. The XRD results reveal the production of composite materials, including well-split materials of nanocrystalline nature, from both constitutive organic and non-organic materials. With the addition of nanoparticles to the cellulose acetate, the real components of electrical conductivity, permittivity, and impedance behaviors exhibit improved performances as a function of frequency dependence. The results of the dynamic mechanical analysis (DMA) showed that the nanocomposite has a significant impact on the DMA parameters at Tg (storage modulus, loss modulus, loss tangent, stiffness, and viscosity modulus) by enhancing interfacial adhesion and optimizing the stress transition demand and power dissipation between the CAmatrix and nanoparticles. Moreover, the antibacterial activity of nanocomposites films is more effective against E. coli (G-ve) bacteria with a relatively wide diameter than against S.aureus (G+ve) bacteria. This ZS/ZO/CA matrix, which is supported by ZS/ZO nanostructures, is intended to be structural mechanical elements in structural engineering, electrochemical solid state systems, and antibacterial. [Display omitted] • A simple, cost - effective, scalable, and effective approach for fabricating ZS/ZO/CA nanocomposites has been developed. • AC conductivity of ZS/ZO/CA nanocomposites, lower filler loadings (0.04, 0.08, and 0.12) exhibited better conductivity than CA. • The addition of CA and ZS/ZO nanoparticles increases internal friction and create excess power dissipation, which improves mechanical and dynamic mechanical characteristics when compared to unaltered CA. • The antibacterial activity of nanocomposites films is more effective against E. coli (G -ve) bacteria with a relatively wide diameter than against S. aureus (G +ve) bacteria.
