Abstract

The present study seeks to synthesize CdS and CdS/M (M = Fe, Mg, Mn) nanoparticles incorporated into a polyvinyl alcohol (PVA)/PEG (polyethylene glycol) blend polymer film, with the objective of developing an advanced nanocomposite for diverse applications in energy storage and radiation shielding. The phases formed in the fillers samples were identified using the X-ray diffraction technique. The structural, morphology, dielectric, and radiation shielding features of the films containing the nanofiller were assessed. Doped blend with CdS/Fe demonstrated the highest dielectric constant and ac conductivity values. The doped blend including CdS has the greatest energy density values. The relaxation time affected by the kind of filler. The influence of type of filler in host blended polymer on linear attenuation coefficients (LAC), mean free path (MFP), mass attenuation coefficient (MAC), half value length (HVL), tenth value length (TVL), equivalent atomic number (Z_eq), effective atomic number (Z_e_ff), electron density (N_eff), atomic cross-section (ACS), and electronic cross-section (ECS), fast neutron removal cross-section (FNRCS), buildup factor values was examined using Phy-X/PSD program. The obtained results demonstrated that doped blends displayed a propensity to interact with gamma rays instead of merely transmitting through them. Our doped blends exhibit superior neutron shielding properties compared to the undoped PVA/PEG blended polymer. The results indicated that doped blends may serve as viable and interesting nanocomposites for radiation shielding application. Also, CdS/Fe sample can be used in the energy storage capacitance application.

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
