Pushing electromagnetic interference shielding self-enhanced based on smart Ti3C2Tx-WVO2 thermal management composite

Aerogel materials have shown tremendous vistas in electromagnetic interference (EMI) of intelligentized electronics and armaments. However, it is challenging to simultaneously achieve self-enhanced shielding performance and release the accumulation thermal. Herein, an intelligent tunable shielding composite was demonstrated through synergistic dynamic interactions between Ti 3 C 2 T x and tungsten doped VO 2 (WVO 2 ), tactfully transforming the accumulation thermal energy to superiority for enhanced shielding. Additionally, the performances of meticulously engineered Ti 3 C 2 T x -WVO 2 composite from thermal conversion to enhanced electromagnetic shielding have been hierarchically dissected. The composite possessed highly sensitive and dynamically tunable shielding performance (Δ SE  = 13.9 dB, X-band = 8–12 GHz) and high-efficiency thermal management characteristic by virtue of three-dimensional porous Ti 3 C 2 T x skeleton, the phase transition of WVO 2 and energy transformation between Ti 3 C 2 T x and WVO 2 . Furthermore, the composite provides excellent shielding performance (EMI SE  = 42.8 dB). Therefore, this Ti 3 C 2 T x -WVO 2 composite can be a potential candidate in both EMI shielding and tunable shielding fields.
