The films of PVA-PAAm-MgO were prepared with various content (0, 0.02, 0.04) of 30 nm particle size MgO by casting solution method. The structure of PVA-PAAm-MgO composite was examined via FT-IR to determine the activation groups, while the diffusion of MgO nanoparticle inside the prepare blend and the homogeneity were examined using the optical microscope. UV-Visible spectrophotometer that used to recording the transmittance spectra in the range of 300–900 nm. The transmittance decreased with the increasing of MgO nanoparticles content in the PVA-PAAm-MgO composite, while the absorbance increased. The optical constants are determined and the optical energy gap decreased with the increasing of MgO nanoparticle content in the PVA-PAAm-MgO composite.
