Ultralight MXene-based aerogels with high electromagnetic interference shielding performance

This work for the first time reports a freeze-casting route for fabricating an ultralight MXene aerogel ( ρ < 10 mg cm −3 ) without using external supporters. It shows that this route is scalable for producing MXene aerogels with large sizes. These aerogels contain micro-sized pores determined by...

Zusammenfassung:This work for the first time reports a freeze-casting route for fabricating an ultralight MXene aerogel ( ρ < 10 mg cm −3 ) without using external supporters. It shows that this route is scalable for producing MXene aerogels with large sizes. These aerogels contain micro-sized pores determined by the morphology of ice crystals and demonstrate strong absorption ability for various organic solvents. More strikingly, they show excellent EMI shielding performance (up to 75 dB) with extremely low reflection (
