“…In this regard, it has been reported that ternary nanocomposites based on polypropylene CdO and bentonite presented an increase of the HVL and mass attenuation coefficients to gamma radiation [82]. In the case of silicone elastomers, the preparation of silicone rubber composites based on (polydimethylsiloxane), bismuth (III) oxide, and hexagonal boron nitride (hBN) with shielding properties against neutron, X, and gamma radiations was reported [83]. The shielding properties of poly (vinyl butyral) containing Bi 2 O 3 @BaZrO 3 also have been studied, and it was observed that they were significantly increased [84].…”

This paper revises the use of polymer nanocomposites to attenuate high-energy electromagnetic radiation (HE-EMR), such as gamma radiation. As known, high-energy radiation produces drastic damage not only in facilities or electronic devices but also to life and the environment. Among the different approaches to attenuate the HE-EMR, we consider the use of compounds with a high atomic number (Z), such as lead, but as known, lead is toxic. Therefore, different works have considered low-toxicity post-transitional metal-based compounds, such as bismuth. Additionally, nanosized particles have shown higher performance to attenuate HE-EMR than those that are micro-sized. On the other hand, materials with π-conjugated systems can also play a role in spreading the energy of electrons ejected as a consequence of the interaction of HE-EMR with matter, preventing the ionization and bond scission of polymers. The different effects produced by the interactions of the matter with HE-EMR are revised. The increase of the shielding properties of lightweight, flexible, and versatile materials such as polymer-based materials can be a contribution for developing technologies to obtain more efficient materials for preventing the damage produced for the HE-EMR in different industries where it is found.

In order to solve the problem of poor thermal conductivity of polymer-based radiation shielding composite materials, h-BN@PDA@PbWO 4 hybrid powders were prepared by combining h-BN with high thermal conductivity and PbWO 4 with γ shielding. With the assistance of polydopamine, PbWO 4 particles were synthesized in situ on the h-BN surface. The effects of h-BN@PDA@PbWO 4 on thermal conductivity, γ-ray shielding, and mechanical properties of chloroprene rubber were studied. The results showed that the hybrid particles had better dispersibility than the pure mixing of h-BN and PbWO 4 in chloroprene rubber and significantly improved the thermal conductivity gamma-ray shielding performance and mechanical properties of CR composites. When the filler content of the hybrid powder reaches 40 wt%, the thermal conductivity of the composite is about 3.16 times that of the pure CR. The γ shielding rates at 86.5 KeV and 105.3 KeV photon energies increase by 14.14% and 17.61% compared with the pure CR. Compared with pure CR, the tensile strength of the composites increased by 4.79 MPa, and the elongation at break decreased slightly. These were because h-BN@PDA@PbWO 4 shows had an excellent synergistic effect in CR substrate. The new kind of CR/h-BN@PDA@PbWO 4 composite can be used for thermal management and gamma shielding.

We report here the development of multifiller nanocomposite containing gadolinium oxide and bismuth nanofillers with enhanced X-ray attenuation property. The mass attenuation coefficient of the nanocomposite is found to be 5.26 (X-ray attenuation: 95%) and 2.22 cm 2 /g (X-ray attenuation: 71%), respectively, under dental and lung X-ray scan conditions. Fourier transform infrared spectroscopy confirms the interfacial interaction between Gd 2 O 3 nanofillers and the polymer matrix through hydrogen bonding. Atomic force microscopy images of the nanocomposite show a smooth and uniform topography with an average surface roughness of~19 nm. Thermogravimetric analysis confirms the thermal stability of the nanocomposite upto 384 C. The enhanced X-ray attenuation property of the nanocomposite is attributed to the good interfacial bonding, dual k-edge effect of nanofillers and their uniform distribution within the polymeric matrix. Therefore, this nanocomposite is a promising material for diagnostic X-ray shielding, especially as, thyroid collar, gonad shield, aprons, gloves, and so on.
