Ameliorating and tailoring the morphological, structural, and dielectric features of Si3N4/CeO2 futuristic nanocomposites doped PEO for nanoelectronic and nanodielectric applications

The present study objects to enhance the morphological, structural and dielectric properties of silicon nitride(Si3N4) and cerium oxide(CeO2) nanocomposites doped polyethylene oxide(PEO) as promising nanomaterials to be useful in a variety of nanoelectronics and nanodielectric applications such as pressure sensors, capacitor, and others applications. The PEO/Si3N4/CeO2 nanocomposites have been fabricated via casting process. The PEO/Si3N4/CeO2 nanocomposites have remarkable characteristics compared with other nanocomposites including excellent dielectric characteristics, inexpensive, superior chemical, and physical properties. The structural properties of PEO/Si3N4/CeO2 nanocomposites included FTIR, FE-SEM, and optical microscope(OM). The dielectric properties were examined at frequency range from 100 Hz to 5 MHz. The results of dielectric properties showed to improve in the dielectric parameters of PEO with the increase in Si3N4/CeO2 nanocomposites content. The dielectric properties of PEO/Si3N4/CeO2 nanocomposites were altered with rising frequency. The dielectric constant and electrical conductivity enhanced to about 68.2
