“…Making the fillers of the polymeric matrixes in the nano scale can dramatically enhance mechanical, thermal, electrical and optical properties of the polymeric composite 14,15 . Similarly, applying nano-scaled fillers into polymer matrices is also efficient in attenuating radiation 16 since nanomaterials are more uniform and have less agglomeration in the composite and therefore can enhance the shielding ability of material 17 .…”

In the present work, high density polyethylene (HDPE) matrix mixed with micro-sized and nano-sized Cadmium oxide (CdO) particles of different concentrations were prepared by compression molding technique. The aim of the study is to investigate the effect of particle size and weight percentage of CdO particles on the gamma radiation shielding ability of CdO/HDPE composites. The mass attenuation coefficients of pure HDPE, micro-CdO/HDPE and nano-CdO/HDPE composites were evaluated at photon energies ranging from 59.53 keV to 1408.01 keV using standard radioactive point sources [241Am, 133Ba, 137Cs, 60Co and 152Eu]. Adding micro and nano CdO particles to the HDPE matrix clearly increases the mass attenuation coefficients of the composites and the improvement is more significant at low γ-ray energies. The effect of particle size of CdO filler has an important role on the shielding ability of the composite. The experimental results reveal that, the composites filled with nano-CdO have better γ-radiation shielding ability compared to that filled with micro-CdO at the same weight fraction. A relative increase rate of about 16% is obtained with nano-CdO content of 40 wt% at 59.53 keV, which attributed to the higher probability of interaction between γ-rays and nanoparticles. From this study, it can be concluded that nano-CdO has a good performance shielding characteristic than micro-CdO in HDPE based radiation shielding material.

“…In addition, the figure shows that the absorbance increases with the concentration of PbO 2 nanoparticles. This behavior is attributed to the agglomeration of nanoparticles with increasing the concentration and the number of charge carriers [14]. Figure 3 shows the relationship between the absorption coefficient of the (PVA-PAA) blend for different weight percentages of PbO 2 nanoparticles and the photon energy.…”

Polymer nanocomposites have been used in many applications such as a fabrication of protective enclosures for humans and devices at nuclear power plants and hospitals. The aim of this paper is the preparation of novel polymer nanocomposites with high linear attenuation coefficients for nuclear radiation shielding. We have produced the nanocomposites of polyvinyl alcohol, polyacrylic acid, and lead oxide nanoparticles with various concentrations of components and have studied their optical properties. As the concentration of PbO2 nanoparticles increases, the absorbance of a polymer blend and the optical constants increase, whereas energy band gap decreases. The tests of the nanocomposite for the gamma radiation shielding showed that it has high attenuation coefficients for gamma radiation.

“…While the majority of the explored ones focused on inorganic materials whether they are metals or semiconductors. Some of these: Ag [19], Sn [20], CdS [21], Ag 2 S [3], SnS [6], CdSe [22], ZnS [23], Co x Fe 3−x O 4 [24], CNTs [9] and others [24,25]. The majority of these previous studies are based on controlling the concentration of the filler (weight ratio percentage: wt.%) to the host polymer.…”

The optical properties of polyvinylpyrrolidine (PVP) polymer have been enhanced using ternary Zn 1-x Sn x S as a filler for UVregion optical applications. Solution casting technique is used to prepare different Sn molar ratios (x: 0-0.3) in Zn 1-x Sn x S filled PVP polymeric composite films (1.0 wt.%). SEM, FT-IR and UV-visible-NIR spectrophotometry is utilized to characterize the optical properties of the plain PVP and polymeric composite films. SEM images reveal the homogeneous dispersion of the filler (Zn 1-x Sn x S) in the host PVP matrix. The FT-IR spectroscopic measurements ensure the successful interaction of ternary Zn 1-x Sn x S material and the host PVP polymer. The cut off transmittance edge is shifted from 260 nm (host PVP) to 390 nm (polymeric composite). The direct optical energy bandgap of the prepared polymeric composite films are shifted from 4.78 eV (plain PVP) to 3.45 eV for Zn 0.7 Sn 0.3 S polymeric composite film. An enhancement of the refractive index (n) and the optical conductivity (σ opt.) of the polymeric composite films is achieved as compared with those of the plain one. The single oscillator (E 0) and dispersion (E d) energies of the polymeric composite films were determined using Wemple and DiDomenico (WDD) model. The prepared polymeric composite films are strongly recommended for UV-region optical applications.
