Abstract
In order to explore their potential applications in advanced materials,
this study examines the optical, electrical, and viscosity properties of
polyvinyl alcohol (PVA) films embedded with chromium oxide (Cr₂O₃)
nanoparticles. In order to assess the impact of different Cr3O₃ nanoparticle
concentrations on the material's characteristics, PVA films were created using
the solution casting method. The optical characteristics were examined using
UV-Vis spectroscopy, which showed a marked decrease in optical transmittance
with increasing nanoparticle concentration, suggesting increased light
absorption. The semiconducting nature of the nanoparticles was attributed to
the improvement in electrical conductivity observed with an increase in Cr₂O₃
content, as measured by means of a four-point probe method. The measurement of
the viscosity of the PVA-nanoparticle solution shows that the viscosity
increases with the addition of Cr₂O₃, indicating that the viscosity is related
to the interaction between the nanoparticles and PVA chains. The interaction of
the films' optical, electrical, and viscosity properties points to potential
uses in sensors, optoelectronic devices, and materials for nanocomposite
materials with adjustable characteristics.
