Metal–organic framework-derived C/Co/Co3O4 nanocomposites with excellent microwave absorption properties in low frequencies
To improve the microwave absorption performance of functional coatings, metal–organic framework (MOF)-based nanocomposites were synthesized via a simple method, including a two-step cooling process. Derived from the ZIF-67 precursor, the nanocomposites consist of C, Co, and C 3 O 4 , and all the thr...

The maximum reflection loss (RL) of CCCO-800 can reach − 84.75 dB at 6.61 GHz, and the effective absorption bandwidth (RL < -10 dB) can be as wide as 8.5 GHz. With the absorber thickness ranging from 1.0 to 5.0 mm, the effective absorption bandwidth of CCCO-800 can cover one half of S band and the whole C, X, and Ku bands. These results show that with an appropriate process control, the nanocomposite absorber can achieve remarkable microwave absorption performance, which makes this type of nanocomposite promising as a functional coating for both civil and military applications.</description><identifier>ISSN: 0957-4522</identifier><identifier>EISSN: 1573-482X</identifier><identifier>DOI: 10.1007/s10854-020-03721-z</identifier><language>eng</language><publisher>New York: Springer US</publisher><subject>Absorbers ; Attenuation ; Characterization and Evaluation of Materials ; Chemical composition ; Chemistry and Materials Science ; Cobalt oxides ; Heat treatment ; Impedance matching ; Low frequencies ; Materials Science ; Metal-organic frameworks ; Microwave absorption ; Military applications ; Nanocomposites ; Optical and Electronic Materials ; Process controls ; Properties (attributes) ; Superhigh frequencies</subject><ispartof>Journal of materials science.
