[Display omitted] •RGO-Ti3C2TX with hierarchical structure and high EMI shielding efficiency was gained.•Fire-resistance and EMI shielding performance of RGO-Ti3C2TX were investigated.•EMI shielding mechanisms of RGO-Ti3C2TX were concluded. Multilayer porous reduced graphene oxide (RGO)-Ti3C2TX composite papers were fabricated by simple evaporation-assisted self-assembly and hydrazine hydrate vapor reduction. Ti3C2TX is embedded between RGO lamellaes through hydrogen bonds. The chemical structure and morphology of RGO-Ti3C2TX are investigated by X-ray diffraction, Fourier transform infrared spectra and scanning electron microscopy. The composite papers with excellent electromagnetic interference (EMI) shielding efficiency (SE) can be obtained by controlling the loading amount of Ti3C2TX and the mass of GO-Ti3C2TX suspension. When the Ti3C2TX content is 3 wt% and the thickness of composite is 1.46 mm, the obtained RGO composite paper presents a total EMI SE of 45.4 dB in the 8.2–12.4 GHz (X-band). Simultaneously, the RGO-Ti3C2TX composite papers maintain fire-exposure stability. The ingenious combination of fire-resistant skeleton structure and porous conductive framework provides an effective method for fabricating RGO-based superb EMI shielding materials applied in the elevated temperature field.
