ABSTRACT In this study, an advanced approach to synthesizing wavy ZnO–cellulose/chitosan@Cu 2+ nanocomposites with improved functionality and conductivity was semi‐dissolving chitosan as a dual‐functionality template. The template method uses form semi‐porous structures ethylene glycol the solvent crystallization agent for hybrid nanostructures. surface morphology, stability, conductive nano‐nanostructures significantly improve microstructural, electrical, antimicrobial properties of Cu‐doped ZnO–cellulose/chitosan formed composite morphology thermal are characterized by thermogravimetric analysis (TGA) field emission scanning electron microscope (SEM–EDX). revealed that nanostructures exhibited steady‐state plateau at low frequencies, which represents DC conductivity, while transferred frequency‐dependent increase higher frequencies due hopping conduction mechanism, Ac conductivity. impedance spectroscopy represented Cole–Cole indicated non‐Debye relaxation processes. equivalent circuit parameters estimated different samples showed segmental capacitance (C1) resistance (R1) values ranging from 4.5665 × 10 −11 F 2.3882 −10 4.9 6 Ω 5.244 5 Ω, Cu concentration increased zero (A0) 4 mol%(A2), respectively. activity using Well diffusion technique. demonstrated inhibition zone diameters 19 31 mm against various microorganisms, including 30 Aspergillus fumigatus 28 Escherichia coli A3 (6 mol% ). These findings suggest can be utilized in biomedical fields such wound dressings, environmental conservation, food packaging, coatings.
