Electromagnetic interference (EMI) shielding materials with excellent flexibility & mechanical properties, and outstanding thermal conductivity have become a research hotspot in functional composites. In this work, the“sol-gel-film conversion technique” is used to assemble polyetherimide functionalized Ti3C2Tx nanosheets (f-Ti3C2Tx) with poly(p-phenylene-2,6-benzobisoxazole) (PBO) nanofibers (PNFs), followed by dialysis and vacuum drying to prepare the f-Ti3C2Tx/PNFs films with lamellar structures. When the loadings of f-Ti3C2Tx is 70 wt%, the f-Ti3C2Tx/PNFs film presents the optimal comprehensive properties, with EMI shielding effectiveness (SE) of 35 dB and specific SE/thickness ((SSE, SE/density)/t) of 8211 dB·cm2/g, tensile strength of 125.1 MPa, in-plane thermal conductivity coefficient of 5.82 W/(m·K), and electrical conductivity of 1943 S/m. After repeated folding for 10000 cycles, the EMI SE and tensile strength of f-Ti3C2Tx/PNFs films still maintain at 33.4 dB and 116.1 MPa, respectively. Additionally, f-Ti3C2Tx/PNFs film also shows excellent thermal stability, flame retardancy, and structural stability. It would provide a novel method for the design and fabrication of multifunctional composite films, and greatly expand the applications of MXene and PNFs-based composites in the fields of EMI shielding and thermal management.
