“…Polyethylene/boron carbide composites were fabricated using conventional polymer processing techniques. The sample containing 2 wt% (weight percent) boron carbide composite showed the best radiation shielding measurements (Harrison et al 2008 ). Photon shielding properties for bismuth oxychloride (BiClO) 5, 10, 15, and 20% filled polyester concretes were studied in the energy range of 59.5–1408 keV using an HPGe detector.…”

The rising use of radioactive elements is increasing radioactive pollution and calling for advanced materials to protect individuals. For instance, polymers are promising due to their mechanical, electrical, thermal, and multifunctional properties. Moreover, composites made of polymers and high atomic number fillers should allow to obtain material with low-weight, good flexibility, and good processability. Here we review the synthesis of polymer materials for radiation protection, with focus on the role of the nanofillers. We discuss the effectivness of polymeric materials for the absorption of fast neutrons. We also present the recycling of polymers into composites.

“…By considering negative effect occured from the use of X‐ray radiation, the aspect of radiation protection is undeniably important in order to prevent any harmfull effect to life form and environment . Some efforts include the use of apron for the operator of X‐ray machine and protection around the room and the door where the machine is placed . The common material used in X‐ray radiation door is Pb (black lead) sheets.…”

Summary Manufacture of composite barrier X‐Ray radiation has been carried out by mixing Elastomer Thermoplastic‐Methyl Metacrylate (ETP‐MMA) with Pb3O4. The study was conducted with four variations: the variation of used rubber materials; the variation of rubber filler material composition; the variation of composite distance to the plane X‐rays; and the variations of composites thickness. Characterizations in this research are X‐ray radiation testing, mechanical testing, and scanning electron microscope (SEM) characterization. The characterizations show that the increasing of thermoplastic composition caused to the increasing of cavities, the reducing of radiation adsorption and the enhanching of mechanical properties. The addition of material composition gives an impact to the elevating of composite density, absorption of radiation, and hardness, but the decreasing of composite strength. Both thicker composite and greater distance between X‐ray machine resulting in greater radiation absorption. The best rubber material as the composite is TPE 30%. The largest composition is 500 phr. The optimum composition in the MMA‐TPE 50% is 435.82 phr with 0.4 cm of thickness. The optimum conditions of 50% MMA‐TPE composite with 0.2 cm of thickness is 168.19 cm in minimum distance between composite and X‐ray machine.

After discovering graphene and its extraordinary intrinsic, other graphene-like nanomaterials (GLNs) became a topic of interest to many scientists of the time. Recently, GLNs, nanosheets of sp 2-hybridized atoms arranged in a two-dimensional lattice with impressive thermal, mechanical, and electrical properties, has attracted both academic and industrial interest because it can produce dramatic improvements in properties at very low filler content. Many studies have been performed on GLNs with various applications, including boron nitride nanosheets, transition metal dichalcogenides, and other two-dimensional (2D) nanomaterials. This rapid advance provides a strong appetence for further research on properties of GLNs, including mechanical, electrical and thermal properties and their potential applications in the nanocomposites industry.
