Spectrophotometric Analysis UV-VIS Irradiated Ternary Hybrid PMMA Composite

Abstract

Ternary hybrid composite PMMA matrix with TiO2-Al2O3- ZrO2 as additives were prepared carried out casting method. Range of weight fractions (92-84 wt %) of PMMA, fixed percentage (4%) of TiO2 and range of weight fractions (4-12 wt %) of Al2O3 and ZrO2 were used as started materials. Optical constants were obtained of the prepared samples using spectrometer (UV- VIS). Absorption coefficient, extinction coefficient, refractive index and optical energy gap were calculated. It was noticing of absorption coefficient and extinction coefficient and refractive index values for (PMMA - TiO2- Al2O3) higher than that of (PMMA - TiO2- ZrO2), also, more decreasing optical energy gap values in the first composites than other samples.
