EM pollution has become subject of great concern for the unperturbed working of all electronic systems, medical, scientific and defense equipment. Lightweight composites with the excellent conductivity and sufficient mechanical properties has attracted more attention for electromagnetic interference shielding. In this study, 3D porous Ti3C2/CNT aerogel has been fabricated via bidirectional freeze drying method for the exceptional EMI shielding. The synthesized MXene/CNT aerogels with CNTs content reveals excellent EMI SE of 104 dB with the thickness of 3 mm at 12.4 GHz frequency. The synergistic effect of lamellar and porous structure comprehensively contributes to the outstanding electrical conductivity and superior EMI shielding effectiveness of the aerogels. As designed hybrid aerogels with outstanding electrical conductivity, good mechanical strength and superior EMI shielding performance is a capable contender against the electromagnetic interference.
