Carbon Nanocage-in-Microcage Structure With Tunable Carbon-Coated Nickel as a Microwave Absorber With Infrared Stealth Property.

ABSTRACT: The rational design of microwave absorption (MA) material featuring light weight, wide absorption bandwidth, and infrared stealth property is crucial for military stealth and health protection but remains challenging. Herein, an innovative N-doped carbon nanocage-in-microcage structure with tunable carbon-coated Ni (NC/Ni(HS)) is reported via a reliable Ni-catalyzed and Ni-templated method. The hierarchically hollow structure of nanocage-in-microcage composites can optimize the impedance matching and respond to multiple reflections and scattering of incident microwaves and infrared waves. Moreover, the magnetic Ni nanoparticles improve the synergistic interactions between confined heterointerfaces and promote interfacial polarization. Such an ingenious structure endows NC/Ni(HS) with outst
