Ameliorating and Tuning the Microstructure and Optical Features of PMMA/PS/SrTiO3 Solid State Nanocomposites For Flexible Optoelectronics Applications

Poly-methylmethacrylate (PMMA)-polystyrene (PS) blend doped with strontium titanate (SrTiO3) nanocomposites have been fabricated for optical and optoelectronics applications. The films (PMMA-PS/SrTiO3) were produced using the casting process. The structure and optical features of PMMA-PS/SrTiO3 nanostructures were examined, the structure characteristics of PMMA-PS/SrTiO3 nanostructures included: FTIR and optical microscope. The optical characteristics were recorded at wavelengths (λ) ranging from 260 to 860 nm. The results revealed that when the SrTiO3 NPs ratio reached 5 wt.%, absorbance (A) rose and transmission (T) decreased, making it suitable for a wide range of optical applications. When the SrTiO3 NPs concentration reached 5 wt.%, the energy gap (Eg) of (PMMA-PS) reduced, making PMMA-PS/SrTiO3 nanostructures important for optical and optoelectronics nanodevices. The optical constants(absorption coefficient, refractive index, extinction coefficient, real and imaginary dielectric constants, as well as optical conductivity)were rise with rising concentrations of SrTiO3 NPs. The results revealed that the PMMA-PS/SrTiO3films may be consideredas future nanocomposite to employ in numerous prospective optical and nanoelectronics applications..
