Impact of Nano CdS/Fe Loading Amount on the Dielectric and Radiation Shielding Characteristics of Polyvinyl Alcohol/Polyvinyl Pyrrolidone Blended Polymers

This work employed casting techniques to fabricate polyvinyl alcohol (PVA)/polyvinyl pyrrolidone (PVP) x wt% CdS/Fe blended polymers, aiming to enhance its dielectric and radiation shielding features. The Rietveld refinement analysis was used to figure out the structure of CdS/Fe filler. X-ray diffraction and scanning electron microscopy were employed to study the structure and morphology of the created blended polymers. The doped blended polymer containing 3 wt% CdS/Fe had superior optical dielectric constant values relative to the other samples. The doped blend with 10 wt% CdS/Fe had the highest energy density values among all blends. The relaxation time is influenced by the quantity of CdS/Fe in PVA/PVP blended polymer. All blends displayed a substantial shielding effect at low energies. Blends with elevated concentrations of CdS/Fe demonstrated superior radiation-blocking properties, making them suitable for purposes requiring photon attenuation. The fast neutron removal cross section of the host blend rose with the augmentation of CdS/Fe doping in the blend. The impact of CdS/Fe on the buildup factor and the energy absorption buildup factor for PVA/PVP/x wt% CdS/Fe blended polymers was explored. The formulated blend can be used in capacitive energy storage and radiation shielding fields.
