Lightweight, ultrathin, and flexible electromagnetic interference (EMI) shielding materials with high electromagnetic shielding effectiveness (SE) and excellent mechanical robustness are greatly desired for miniaturized and highly integrated electronics. Herein, for the first time, a freestanding, ultrathin, and flexible Ti3C2Tx/poly(3,4-ethylenedioxythio-phene)-poly(styrenesulfonate) (PEDOT:PSS) composite film with a brick-and-mortar structure is biomimetically designed and fabricated via a vacuum-assisted filtration process. The ultrathin polymeric composite film with a weight ratio 7:1 of Ti3C2Tx to PEDOT:PSS is only 11.1 mu m in thickness but exhibits a high EMI SE value of 42.10 dB. Meanwhile, the tensile strength increases considerably from 5.62 to 13.71 MPa and the corresponding ruptured strain increases from 0.18 to 0.29% compared with pure Ti3C2Tx MXene film, respectively. Moreover, the hybrid film displays a superior conductivity of 340.5 S/cm and an outstanding specific EMI shielding efficiency of 19 497.8 dB cm(2) g(-1). The superior electrical conductivity and specific EMI shielding efficiency imply the excellent potential of the Ti3C2Tx/PEDOT:PSS composite films for ultrathin, lightweight, and flexible EMI shielding materials.
