Influence of MnO2 Nanoparticles’ Addition on Optical Properties of PVA/PEG Blend
0497–0506 (2022)

PACS numbers: 78.20.Ci, 78.40.-q, 78.67.Sc, 81.07.Pr, 81.40.Tv, 82.35.Np

This work is aimed to fabricate the PVA/PEG/MnO2 nanostructure to be used in many applications in electronics and optics. The optical properties of PVA/PEG/MnO2 nanostructure are studied at wavelength range from 200 nm to 800 nm. The experimental results show that the absorbance of PVA/PEG blend increases with the increase in MnO2 nanoparticles’ concentration that may be used for various electronic applications. The extinction coefficient, refractive index, real and imaginary parts of dielectric constants, and optical conductivity of PVA/PEG blend are also increased with the increase in MnO2 nanoparticles’ concentration. The transmittance and energy band gap are decreased as MnO2 concentration increases.

Key words: optical properties, polymer blend, nanocomposites, MnO2, nanostructures.
