Abstract
This study investigates the optical, electrical, and viscosity
properties of polyvinyl alcohol (PVA) films embedded with chromium oxide
(Cr₂O₃) nanoparticles, aiming to explore their potential applications in
advanced materials. PVA films were synthesized through a solution casting
method, incorporating varying concentrations of Cr₂O₃ nanoparticles to evaluate
their effects on the material's properties. UV-Vis spectroscopy was used to
analyze the optical properties, revealing a significant reduction in optical
transmittance with increasing nanoparticle concentration, indicative of
enhanced light absorption. Electrical conductivity was measured using a
four-point probe method, showing an improvement in conductivity as Cr₂O₃
content increased, attributed to the semiconducting nature of the
nanoparticles. The viscosity of the PVA-nanoparticle solution was measured,
demonstrating that the addition of Cr₂O₃ increases the viscosity, which can be
linked to the interaction between PVA chains and nanoparticles. The interplay
between the optical, electrical, and viscosity properties of the nanocomposite
films suggests promising applications in optoelectronic devices, sensors, and
nanocomposite materials with tunable properties.
