Abstract
Designing a material with simultaneous microwave and sound absorption abilities is highly desired to mitigate electromagnetic radiation and noise pollution. However, their further development is highly challenging due to their totally different mechanisms of energy conversion. Here, we fabricate an ultralight and porous composite aerogel composed of cotton-derived nanofibrillated cellulose and MXene (f-Ti3C2TX) nanosheets by directional freeze-drying technology, toward simultaneous microwave and sound absorption. The honeycomb-like biomimetic microstructure of obtained composite aerogel not only allows unidirectional transmission for incident microwaves and sound waves but also induces strong energy…
