| The controlled design of novel materials is driving the increase of innovation in the electrical sector. Because of its numerous uses in electromagnetic interference shielding, medicine, biomedical sensing, structural engineering particularly military buildings, and soundproof buildings, solar cell, electronics devices, and so on, hybrid materials based on magnetite/cellulose nano structure are quite appealing. Because of its multifunctionality and simplicity of integration with existing production processes, magnetite-cellulose core-shell nanocomposites or nanoparticles embedded in polymer matrices have piqued the interest of many researchers. In this study, a new type of composite polyvinyl alcohol membranes with various concentrations of magnetite/cellulose nanostructured core shell was effectively constructed. For all samples, the real component of the dielectric constant (έ), the dielectric loss factor (ɛ″), and the ac conductivity (σac) are measured as a function of frequency from 50 Hz to 5 MHz with an applied voltage of 0.1 V using HIOKI 3532‐50 LCR Hi tester. Using the ultraviolet-visible spectrum, the optical properties of thin films were studied. A decrease in dielectric constants and dielectric losses were found with increasing frequency while AC conductivity increased with increasing frequency for different concentrations of NC/MNPs at room temperature. Because of their superior dielectric performance, these composite membranes have been found to be suitable for use in electronic devices. XRD and FTIR measurements were used to evaluate the effect of magnetite/cellulose nanostructure loading on the crystal structure of the produced composite films. | ||||
