Polyvinyl alcohol (PVA)/starch/graphene oxide nanocomposites containing different ratios of tungsten oxide (WO3) were prepared for use in the medical field as low‐cost, facile, eco‐friendly, and biodegradable low‐energy γ‐ray shielding materials. The effect of different WO3 loading (0, 2, 4, 8, and 12 wt%) on nanocomposites' structural, mechanical, and gamma attenuation properties was studied. X‐ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscope verified the incorporation of WO3 into the nanocomposite matrix. The thermal stability and activation energy of the decomposition of nanocomposites showed continuous improvement with increasing WO3. The maximum tensile strength and elongation of nanocomposites were achieved by incorporating 4 wt% WO3 compared to the lowest tensile strength and elongation at 8 and 12 wt% of WO3, respectively. The good filler distribution inside the polymeric matrix at lower filler loading compared to the creation of voids and agglomeration at higher filler levels explains this behavior. It was found that nanocomposites' calculated mass attenuation coefficient μm (cm2/g) increased with increasing WO3 at different photon energies. Half‐value layer (HVL) and tenth‐value layer (TVL) values fall as WO3 concentration rises. The sample with 12 wt% of WO3 exhibits lower HVL and TVL values and higher μm, demonstrating a more remarkable gamma attenuation ability. Such results endorsed the prepared nanocomposites as low energy γ‐rays attenuation materials in medical fields.Highlights PVA/starch/graphene oxide nanocomposites with different WO3s were fabricated as shielding materials. The impact of WO3 on nanocomposites' mechanical and shielding characteristics was studied Thermal stability of nanocomposites showed continuous improvement with increasing WO3 μm increased with continuously increasing WO3 at different photon energies.

“…This behavior was observed in some previous works. 56,57 It was important to do a thermogravimetric investigation on PVA/starch/GO films to comprehend how WO 3 affects the thermal stability of nanocomposites. TGA curves for PVA/starch/GO films doped with various concentrations of WO 3 are shown in Figure 8.…”

“…In brief, the purpose of this work is to investigate the effect of adding various percentages (0, 10, 15, 25, and 35 wt%) of different nanoparticle sizes of PbO to the polystyrene, particularly, on the structural and mechanical properties. Afterward, a comparative study will be conducted between the results obtained by Obeid et al [36] and the outcome of this study. Furthermore, the new understanding of the relation between particle size and the enhancement of composite properties will allow a beneficial use of PS/PbO nanocomposite in many applications mainly as radiation shielding, where the improvement of the mechanical properties by lead incorporation creates an internal protection system to prevent degradation of the composite due to irradiation, and hence provides a new class of a low-cost light metal-based shields with high strength and a customizable design to conserve space and reduce waste.…”

“…Hence by increasing the PbO loading up to 40 wt%, the stiffness, ultimate tensile strength, and yield stress increase, however, the ultimate tensile strain, tensile energy, and percent elongation at break decrease considerably. Recently, Obeid et al [36] discussed the effect of adding various filler amounts (10, 15, 25, and 35 wt%) of bulk micro-sized WO 3 and two different WO 3 nanoparticles (45 nm and 24 nm) on the mechanical properties of high-density polyethylene (HDPE) polymer synthesized via compression molding technique. The variation of Vickers microhardness H v showed a reverse indentation size effect (RISE) and exhibited a noticeable increase with increasing the WO 3 nanoparticle (24 nm) filler loading up to 25 wt%.…”

Two different sizes of PbO nanoparticles, notably PbO(A) and PbO(B) with sizes of 78 nm and 54 nm, respectively are produced using a high-speed planetary ball milling machine under specific operating parameters. Following, the novel nanocomposite PS/PbO is synthesized using compression molding by embedding 10, 15, 25, and 35 wt% of PbO(Bulk), PbO(A) and PbO(B) into PS separately. The composite is further characterized by Fourier transform infrared spectrophotometer (FTIR), scanning electron microscope (SEM), energydispersive X-ray spectroscopy (EDS) and laser-induced breakdown spectroscopy (LIBS). FTIR results confirm the presence of PbO, and indicate a physical adsorption of the nanoparticle onto the PS matrix surface. SEM, EDS and LIBS analyses reveal a more efficient diffusion of PbO in the PS matrix with the decrease of the nanoparticle size. On the other hand, Tensile and Vickers microhardness tests are performed to investigate the composite's mechanical properties. The stiffness is, indeed, enhanced with increasing weight fraction, as well as with decreasing particle size of PbO. Whereas, the strength of the composite is optimized with 15wt% of PbO. Microhardness test reveals an ISE behavior of the composite, and an increase in H v values with PbO loads up to 15 wt%. Accordingly, by adjusting the filler particle size and concentration, the mechanical properties of the composite are evidently enhanced, increasing their use in a variety of applications such as coating, insulation and radiation shield.

The fast neutron and gamma-ray attenuation characteristics of high-density polyethylene (HDPE) reinforced with boron carbide (B4C), iron oxide (α-Fe2O3), aluminum oxide (Al2O3), iron (Fe), and aluminum (Al) particles were investigated for use as neutron radiation shielding materials. The samples were fabricated from Pure HDPE, HDPE/10% B4C, and HDPE/10% B4C/30% X (X= Fe, Al, α-Fe2O3, and Al2O3) using the compression molding technique. Scanning electron microscope (SEM) has been used to characterize the prepared samples. The mechanical properties of the prepared samples have been investigated. Sample C3 (HDPE/10% B4C/30% α-Fe2O3) shows better mechanical properties than other samples under investigations. 239Pu–Be was used as a source of fast neutrons with a neutron yield of 1.7x106 n/sec and were detected by the Stilbene scintillator. Neutron removal cross-section (ƩR) with dependent parameters, mean free path (MFP) and half-value layer (HVL), of the prepared composites were calculated. In addition, the gamma-ray transmission through the prepared composites has been investigated. As a result, the composite containing 30% iron oxide showed better shielding properties for both neutrons and gamma-rays compared to the other investigated samples. The calculated values of the shielding parameters revealed that the prepared composites can be efficiently used in fast neutrons and gamma rays shielding in fields that use radiation facilities.
