Abstract
Multifunctional microwave absorbing materials are urgently needed in aircrafts due to their harsh service environment. Herein, a rare-earth [email protected] nanofiber aerogel has successfully manufactured to meet this demand. The light aerogel not only exhibits a wide efficient bandwidth (7.44 GHz) and strong reflection loss (−63.7 dB), but also excels in infrared thermal camouflage, self-cleaning, and mechanical strength. These excellent properties are related to the porous construction of the aerogel and plenty of heterogeneous interfaces. This work provides insights into novel ideas for multifunctional microwave-absorbing materials with enormous potential.
