Dielectric Constant properties of Poly (vinyl acetal)/PVA Dispersed with ZnO Nanoparticles

Abstract

Poly 4-methyl benzyledene vinyl alcohol (Poly (vinyl Acetal)) was prepared and characterized with IR spectroscopy and the melting point measured. ZnO nanoparticles were also prepared and with the Atomic Force Microscope (AFM), Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD) characterized, studied and the nanoparticles size were measured. Poly (vinyl acetal)/PVA composite were prepared by ultrasonically mixing with different ZnO nanoparticles percent. Each mixture was fabricated in film and casted in 5x5 cm glass caste. The real and imaginary dielectric permittivity and electric modulus were for the prepared films studied.
