摘要

This work focuses on construction of novel polyvinyl alcohol (PVA)/pyrrolidone (PVP) blend loaded with multi-walled carbon nanotubes (MWCNTs) and multi-phase Zn1–xMgxO/Mn3O4/MnO nanohybrids (x = 0, 0.01, 0.03) for dual optoelectronic and radiation protection applications. The consequence of the loading process on the structure, surface morphology, fluorescence spectra and CIE 1931 chromaticity diagram of the PVA/PVP/MWCNTs/Zn1–xMgxO/Mn3O4/MnO system was examined. The radiation safety properties of PVA/PVP/MWCNTs/Zn1–xMgxO/Mn3O4/MnO composites were analyzed utilizing the Phy-X/PSD package. The linear attenuation coefficient (LAC) values at 15 keV are (1.054, 1.140, 24.656, 24.654, and 24.654 cm–1) and (1.258, 1.361, 34.762, 34.735 and 34.722 cm2 g–1) for pure and loaded blended samples with MWCNTs and MWCNTs/ Zn1–xMgxO/Mn3O4/MnO (x = 0, 0.01, 0.03), respectively. The half-value layer (HVL) and mean free path (MFP) values for the unloaded and loaded blended samples involving MWCNTs and MWCNTs/Zn1–xMgxO/Mn3O4/MnO (x = 0, 0.01, 0.03) are (10.337, 10.280, 9.520, 9.527, 9.530 cm) and (14.914, 14.832, 13.734, 13.744, and 13.749 cm), respectively. At 15 keV, the effective atomic number (Zeff) factor of PVA/PVP grew from 5.798 to 23.179 following the incorporation of Zn1–xMgxO/Mn3O4/MnO in the host sample. The effect of fillers on the fast neutron removal cross-section and buildup factors was assessed.
