The extensive use of wireless communication devices has resulted in severe electromagnetic interference (EMI), which driven the need for advanced EMI shielding materials. In this study, a twin-coated skeleton hybrid aerogel was constructed from para-aramid nanofibers (p-ANFs), MXene (Ti3C2Tx) flakes, and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) chains via freeze-drying route. robust p-ANFs established with unique porous structure reversible compressibility. cloth composed 28 wt% PEDOT:PSS 20 MXene, endowed PEDOT:PSS/MXene/p-ANFs efficient properties. effectiveness (SE) specific (SEE/t) X band (8.2–12.4 GHz) reached 41.27 dB 3063.7 dB·cm2·g−1, respectively. Interestingly, capacity controlled by contents PEDOT:PSS/MXene ratio. Moreover, exhibited outstanding compressive resilience, maximum stress 61.72 kPa under strain 60% after 500 cycles. addition, relationship between deformation power coefficient aerogels constructed. Thus, study provides feasible route fabricating compressibility performance.
