The new polymer-metal composite’s density of 11 g/cc matches that of generally available lead alloy. The effectiveness of radiation shielding is to a large extent determined by a material’s density, radiation absorption of the filler materials (in the case of a polymer-metal composite material), and molecular or crystal structure. WebAug 9, 2024 · The energy density Ue reaches a maximum of 112 J cm −3 for x = 0.3 and 110 J cm −3 for x = 0.4 because of the optimized dielectric properties by the polymorphic nanodomain design. These values are twice as large as the 53 J cm −3 that we measured in the x = 0.0 film, which possesses only R nanodomains. diamond\u0027s h2
