Lightweight Nanocomposites Based on Polypropylene and Aluminum Nanoparticles and Their Shielding Capability to Ionizing Radiation

Electromagnetic interference shielding response and rheological behavior of lightweight nanocomposites based on isotactic polypropylene and Al nanoparticles

“…Nevertheless, what is noticeable is that the shielding capability will be improved with the increase in the electrical conductivity [20,52,55,56]. although the presence of a weak diffraction, ascribed to the (117) reflection of the γ form, is also observed [21]. Figure 5 points also out a noticeable decrease of the synchrotron X-ray radiation that reaches the detector, as much as the Al content is increased in the final material.…”

“…The study of the dielectric behavior of these nanocomposites demonstrated [21] that conductivity increased with frequency and was enlarged slightly with incorporation of Al nanoparticles at a given frequency. Nevertheless, dependence on frequency was rather similar for the nanocomposites compared with that exhibited by the neat iPP matrix.…”

“…Nevertheless, the increasing market price of copper presents some inconveniences. As an alternative, lighter and cheaper Al nanoparticles were employed to obtain iPP−Al (nano)composites [21]. They showed up to a 99% attenuation of the electromagnetic radiation at the same frequency (2 EHz).…”

Effects of the γ‐irradiation strength and basalt additive content on the mechanical performance and dielectric response of polypropylene films

“…Resistant additives to the polymer, such as basalt and metal oxides, can eliminate this effect. A great deal of scientific research has also been done to ensure that PP and its composites are suitable radiation‐shielding materials . In this respect, a low‐cost and high‐performance engineering polymer, PP, was chosen as a host matrix for improving its mechanical and dielectric properties via an electromagnetic irradiation process.…”

“…A great deal of scientific research has also been done to ensure that PP and its composites are suitable radiation-shielding materials. 9,10 In this respect, a low-cost and high-performance engineering polymer, PP, was chosen as a host matrix for improving its mechanical and dielectric properties via an electromagnetic irradiation process. The influence of electron-beam and γ-ray irradiation of commercial PP films' dielectric, mechanical and thermal properties were studied by Pawde and Parab 11 and Abiona and Osinkolu, 3 respectively.…”
