Abstract Electromagnetic interference (EMI) shielding materials with low electromagnetic (EM) waves reflection characteristics are ideal for blocking EM radiation and pollution. Materials reflectivity must be constructed using excellent absorption properties. However, simultaneously possessing both EMI performance remain scarce, consequently, multilayer structures need to developed. Poly(p‐phenylene–2,6–benzobisoxazole) nanofibers (PNF) prepared by deprotonation. PNF combined MXene heterostructure MXene@Ni in‐situ growth; MXene@Ni/PNF acts as an layer while MXene/PNF reflective layer. Finally, (MXene@Ni/PNF)–(MXene/PNF) aerogels layer‐by‐layer freeze‐drying based on the layered modular design concept. Experimental characterizations revealed that enable efficient absorption‐reflection‐reabsorption of waves, effectively eliminating EMI. When mass ratio Ni in is 1:6 fraction 80 wt.%, exhibit (71 dB) a very coefficient (R = 0.10). Finite element simulations verified developed asymmetric structural achieve high characteristics. In addition, display infrared camouflage ability.
