“…This result agrees with the lower electrical resistance that the Hyb samples showed compared to the composites with GNPs, as shown in Figure 4. In general, the X-band EMI shielding effectiveness reported herein, is comparable to other similar literature works on poly(methyl methacrylate)−GNP nanocomposites 56 or epoxy−GNP nanocomposites. 57 It is worth noticing that the 15 wt % Hyb samples display shielding effectiveness higher than 20 dB, which is the threshold for numerous commercial applications.…”
