Impact of SnS2/Fe Nanofiller on PVA/PVP Blended Polymer: Structural, Electrical and Radiation Shielding Properties

Structure and morphology of PVA/PVP/SnS₂/Fe-doped blends were considered employing X-ray diffraction and scanning electron microscopy. Maximum dielectric value was attained in the PVA/PVP/1 wt% SnS₂/Fe blended polymers. Relaxation time was affected by the amount of filler. Energy density and AC conductivity were improved as the blend loaded with 5 wt% SnS₂/Fe. Radiation parameters for all blends were explored using the Phy-X/PSD program. All blends exhibited relatively elevated MAC values at lower energy, specifically 15 keV. MAC diminished to 0.095 cm²/g for all blends when energy increased to 0.5 MeV. Doped blends had enhanced photon attenuation capacities. Doped samples exhibited superior attenuation properties. The doped blend with 10 wt% SnS₂/Fe required the least thickness to attenuate photons at select energies relative to other blended polymers. At 0.5 MeV, the TF values were 89.33%, 89.03%, 89.83%, 88.02%, and 86.77% for samples with x values of 0, 1, 3, 5, and 10, respectively. At 5 cm thickness, TF % values were 56.88, 55.92, 58.50, 52.83, and 49.17 for samples with x values of 0, 1, 3, 5, and 10, respectively. At a distance of 1 cm, RPE values were 10.67%, 10.97%, 10.17%, 11.98%, and 13.23% for samples with x values of 0, 1, 3, 5, and 10, respectively. At 5 cm, RPE values rose to 43.12%, 44.08%, 41.49%, 47.17%, and 50.83% for the corresponding blends, respectively.
