Increasingly popularity of electronic devices and wireless apparatus requires advanced materials to cope with severe electromagnetic wave pollution. Herein, magnetic EM wave shielding material, Ti₃C₂T_x/Fe₃O₄/aramid nanofibers composite paper, composed of low-dimensional Ti₃C₂T_x flakes and carboxylation Fe₃O₄ nanoparticles, was developed via vacuum-assisted filtration. At the meanwhile, uniform dispersion of components was achieved to overcome magnetic through ingenious electrostatic force regulation originated from negative functional groups. The Ti₃C₂T_x/Fe₃O₄/aramid nanofibers composite paper exhibited suitable magnetic performance, outstanding electrical conductivity, and excellent electromagnetic interference shielding performance. Moreover, the Ti₃C₂T_x/Fe₃O₄/aramid nanofibers composite paper demonstrated favorable mechanical properties, whose tensile strength and Young’s modulus reached 132.2 ± 2.1 MPa and 5.23 ± 0.14 GPa, respectively. The combination of electromagnetic shielding capacity (derived from Ti₃C₂T_x flakes, carboxylation Fe₃O₄ nanoparticles) and mechanical properties (derived from aramid nanofibers) provided feasible strategy in fabricating advanced EMI shielding composite with astonishing comprehensive performance.
