Thickness Influence on the Optical Properties of (PMMA-PbO) Nanocomposites

In all technological fields, nanotechnology is one of the most popular subjects of contemporary study and development. polymer science and technology are included, and research in this field encompasses a wide range of problems. because the key size scale for current devices is now less than 100 nanometers, this would encompass microelectronics (which may now be referred to as nanoelectronics). this paper includes the effect of thickness of the nano-composite (polymethyl methacrylate - lead oxide) on the optical properties and preparing (pmma-pbo) nanocomposite by adding 1wt% of lead oxide topmma that have been prepared at room temperature, by using the casting method.the thicknesses of the films were determined using an electronic digital device (micrometer) and found to be (60,120, and 220) μm. ftir and optical properties of nanocomposite (pmma-pbo) were examined. the absorbance, absorption coefficient, refractive index, extinction coefficient, real and imaginary parts of the dielectric constant of (pmma-pbo) nanocomposites increased with increased film thickness, according to the experimental results. with increasing film thickness, the transmittance, and energy band gap decrease.
