This project involves the studying of both optical and electrical properties for the poly methyl methacrylate/zinc oxide composite. These materials were selected because they have an industrial applications and available in local market.Zinc oxide powder with different concentration (4, 8, 10 and 12) % from the total weight was mixed carefully with PMMA. Manual mixing and molding processes were used to prepare the circular shape composites with the same diameter and thickness at the ambient temperature by using ultra sonic water bath.The structural composites are studied via X-ray diffraction technique, where the results showed absent any chemical reaction between the matrix and enhancement zinc oxide when they compared with the reference charts.Basic chemical groups were diagnosis via Fourier transfer infrared technique. The absorption peaks as a function of wavelength number found at the same wave number for PMMA and the PMMA/ZnO composite with different concentration.UV-visible technique was used to investigate the optical properties, the result pointed that the refractive index and energy gap values suffered reduction due to zinc oxide particles increasing, the absorption and extinction coefficients increased when the zinc oxide particles increased. High frequency LCR meter was used to study the dielectric properties; it was found that dielectric constant and dielectric loss suffered decreasing with the increasing of zinc oxide particles in the PMMA
