The lightweight, thin and effective electromagnetic shielding materials are needed with the growing numbers of electronic devices with small size. Here, the lightweight and ultrathin TiO 2 -Ti 3 C 2 T X /graphene film with the range of 5.25–9.17 μm of thickness was prepared by vacuum filtration and pyrolysis. The electrical conductivity and electromagnetic interference shielding effectiveness (EMI SE) of TiO 2 -Ti 3 C 2 T X /graphene film with different amount of Ti 3 C 2 T x were evaluated. The surface resistance and EMI SE reach 7.5 Ω/sq and 28 dB, respectively. A realistic parameter of special shielding effectiveness/thickness (SSE/t) is up to 30291.43 dB cm 2 g −1 when density and thickness of the TiO 2 -Ti 3 C 2 T X /graphene film are considered. This work provides the strategy to produce lightweight and ultrathin film for effective EMI shielding.
