| 英文摘要 | Lightweight spongy bone-like graphene@silicon carbide (SiC) aerogels were fabricated by the directional freeze-casting of graphene oxide (GO) coated SiC whiskers slurry and thermal reduction of GO@SiC aerogels. The unique hierarchically ordered structure of graphene@SiC aerogels is formed by graphene wrapped SiC whiskers, such a structure possess great advantages such as low density (72 mg/cm(3)) and high microwave absorption performance for aerogels. The minimum reflection loss of typical sample achieves -47.3 dB at 10.52 GHz with a thickness of 3 mm, and the effective bandwidth of reflection loss <= -10 dB can reach 4.7 GHz. These results indicate that the novel graphene@SiC aerogels is an optimal material for high-performance microwave absorption application in aeronautics.; Lightweight spongy bone-like graphene@silicon carbide (SiC) aerogels were fabricated by the directional freeze-casting of graphene oxide (GO) coated SiC whiskers slurry and thermal reduction of GO@SiC aerogels.
