abstract = {Flexible electromagnetic interference (EMI) shielding films with high stability have shown promising prospect in harsh working conditions such as military, communication, and special protection fields. Herein, flexible aramid nanofibers@polypyrrole (ANF@PPy) films with high stability were easily achieved by the in-situ growth of PPy on the surface of ANF and the subsequent pressured-filtration film-forming process. When the amount of pyrrole (Py) monomer is 40 µL, the ANF@PPy (AP40) film exhibited excellent EMI shielding performance with shielding effectiveness (SE) of 41.69 dB, tensile strength of 96.01 MPa, and fracture strain of 21.95% at the thickness of 75.76 μm. Particularly, the anticipated EMI shielding performance can be maintained even after being heated at 200 °C in air, soaked in 3.5% NaCl solution, repeated folding for one million times, or burned directly, indicating superior environmental durability in harsh conditions. Therefore, it is believed that the ANF@PPy films with high stability offer a facile solution for practical protection for high-performance EMI shielding applications.}
