▎ 摘　　要

The rapid development of high performance detection technology promotes the innovation of stealth technology moving towards the direction of multi-band compatibility, but suffers great challenges. Especially for the widely used radar detection and infrared detection, how to overcome the contradiction between their corresponding stealth materials and develop high-performance stealth materials with microwave-infrared compatible property is extremely urgent. Herein, flexible cellular reduced graphene oxide aerogels modulated by antimony tin oxide (ATO/rGO) have been synthesized by self-assembly, which demonstrate excellent microwave-infrared stealth compatibility. Remarkably, the aerogel exhibits dual-absorption in microwave stealth caused by strong interface polarization, achieving the maximum reflection loss (RL) of -40.92 dB at 11.36 GHz coupled with another absorption peak of -19.82 dB at 16.64 GHz and a broadest effective absorption bandwidth of 9.8 GHz covering the X band and Ku band, which can be verified by electromagnetic finite element method simulation. Moreover, trace amount of loss components ATO in conductive network structure guarantee the low infrared emissivity (0.383) and thermal insulation synchronously, which is the key to compatibility with infrared stealth. The light ATO/rGO aerogels demonstrate the great prospect for anti-detection and security protection, providing a novel approach for multispectral compatible stealth.
