With the rapid advance of electronics, the light, flexible and multifunctional composite films with high electromagnetic interference (EMI) shielding effectiveness and excellent thermal management are highly desirable for next-generation portable and wearable electronic devices. Herein, a series of flexible and ultrathin natural rubber/MXene/carbon nanotubes (NR/MXene/CNTs) composite films with sandwich structure are constructed layer by layer through a facile vacuum-assisted filtration method for EMI shielding and Joule heating application. The fabricated NR/MXene/CNTs-50 composite film, with NR/MXene as inner layer and NR/CNTs as out layers, not only has high EMI shielding efficient, but also has excellent comprehensive mechanical properties at the thickness of only 200 μm. In addition, the superior environmental durability, high electro-thermal conversion efficiency, hydrophobicity and fine performance stability after periodic cyclic bending make the film possess more value in practical application.
