【 摘 要 】

tsLarge-area, lightweight, ultra-flexible, and robust crosslinked MXene-coated PI porous composites were manufactured via a scalable and facile approach.In addition to the hydrophobicity, anti-oxidation and extreme-temperature stability, excellent electromagnetic interference shielding performance was achieved because of the high-efficiency utilization of the building units and microstructure.Moreover, the highly flexible composite foams exhibited excellent electrothermal and electromechanical sensing performance, demonstrating promising perspectives in next-generation flexible electronics, aerospace, and smart devices.
