Optical and Electrical Properties of Polystyrene/Poly‐methyl methacrylate Polymeric Blend Filled with Semiconductor and Insulator Nanofillers

The present study deals with the effect of adding different fillers (semiconductor and insulator) on a polystyrene (PS)/poly-methyl methacrylate (PMMA) polymer blend using casting method. A constant content (1 wt%) semiconductors [multiwalled carbon nanotubes (MWCNTs), polyaniline (PANI), zinc oxide nanoparticles (NPs), titanium dioxide NPs] insulator [silicon is used. Transmission electron microscopy images for MWCNTs show that most have an average diameter 7–11 nm. Moreover, size all metal nano-oxides almost 20 nm confirmed by X-ray diffraction. Fourier-transform infrared spectroscopy confirms formation interaction between PS/PMMA fillers. structural, mechanical, optical, dielectric properties prepared nanocomposites are studied tools. Optical characteristics such as absorbance, reflection, bandgap energy (E g), optical components (real imaginary) studied. These results reveal pure 20PS/80PMMA film has E g(direct) = 4.46 eV, which drops incorporated into blend. addition MWCNTs, PANI to improves electrical conductivity due growth conductive paths filler blending matrix.
