Dielectric and dynamic antibacterial investigations of organic–inorganic conductive membranes based on oxidized cellulose with BNKT nanoceramics

Abstract The development of eco-friendly materials for advanced applications is highly demanded. current study focuses on the preparation conductive membranes based tricarboxylic cellulose (TCC) loaded with cubic bismuth sodium titanate (BNKT) nanoceramics. FTIR, SEM, and EDX analyses confirm presence BNKT membranes. electrical response cellulose/xBNKT (x = 5, 10, 15, 20% wt/wt) membrane investigated using impedance spectroscopy. real part (Z′) imaginary (Z″) complex are studied as a function frequency (4Hz ~ 8MHz) temperature (20 160 °C) different compositions. Impedance modulus studies reveal Debye-type relaxation phenomenon. dielectric manifest promising properties. bactericidal performance all nanomembranes evaluated. nanomembrane (C20) exhibits activity against Gram-negative Gram-positive bacteria, 6 log CFU reductions observed after an exposure time 180 min. Treatment C20 shows highest amounts protein efflux. results indicate that layer eradicated bacterial cells. findings suggest recommended intelligent innovative antibacterial nano-system bio-applications.
