Fig. 4: Janus aerogels for EMI shielding.
a EMI shielding characteristics of Ti3C2Tx/GO (20 wt% GO) and mGO/GO (50 wt% GO) Janus aerogels prepared by two 200 µm nozzles. b Schematic illustration of internal scattering in Ti3C2Tx/GO (20 wt% GO) and mGO/GO (50 wt% GO) Janus aerogels from macro-to micro-scale. c, d EMI shielding characteristics of copper coated magnetic/conductive Janus aerogels. This shield consists of a 3 mm Janus aerogel covered with 0.05 mm conductive copper tape from one side. The Janus aerogel of this shield is designed in a way that the magnetic parts’ volume is larger than the conductive domain. c summarizes the EMI shielding characteristics of the aerogel sides, while d showcases those characteristics that belong to the copper side of the shield. e A comparison of the SET vs. A of the magnetic/conductive Janus structures with the previous best practices in the literature. For more information, see Table S1.
