A type of lightweight and flexible graphene/multi‐walled carbon nanotube (MWCNT) hybrid buckypaper (BP) is fabricated, which show superior shielding effectiveness (SE) of electromagnetic interference and without polymer. The EMI SE of graphene/MWCNT hybrid BP with thickness of 130 μm is up to ∼51 dB at 8 GHz, which is much higher than that of pure MWCNT BP with same thickness (∼32.5 dB) and the best electrical conductivity is up to 10,000 S/m. More important, the improvement in EMI SE is contributed to the SE absorption, while the SE reflection is almost unchanged. This paper‐like material is smooth, tough, and flexible enough to be attached on the complex curved surface structure. A facile way to fully develop graphene and MWCNT in lightweight and flexible EMI shielding materials and devices is provided here.
