| Summary: | MXene-based nanocomposites are potential candidates to meet the escalating challenges posed by EMI and radiation. Despite the promising characteristics of MXene, the synthesis of flexible and long-term stable polymer-MXene nanocomposites with exceptional EMI shielding is considerably challenging. This study investigates novel PANI/Ta2C MXene nanocomposites for EMI shielding. Chemically synthesised PANI/Ta2C MXene nanocomposites are characterized, and their flexible free-standing films are prepared. PANI/Ta2C MXene nanocomposites demonstrate synergistic behaviour to shield EMI, superior to either component. A free-standing film of PANI/Ta2C nanocomposite I exhibits an excellent shielding efficiency of 58 dB over a frequency range from 7 to 13 GHz, which corresponds to 99.999% shielding effectiveness and specific shielding performance (SSE) as high as 580 dB/mm. These ultra-thin, lightweight and flexible free-standing films may find application in next-generation EMI shielding solutions for wearable technology, electronic packaging, and aerospace applications. |
