Ultralight and Ultrabroadband CoFe2O4/rGO/CNR Composites
Listed in ScienceDB
The development of high-performance electromagnetic microwave (EMW) absorbers with lightweight characteristics is critical for addressing electromagnetic pollution.
Description
In this work, CoFe2O4/reduced graphene oxide/carbon nanoribbon (CFO/rGO/CNR) composite aerogels were successfully fabricated via a combination of hydrothermal and solution mixing strategies. The resulting composite possesses a unique three-dimensional (3D) conductive skeleton formed by rGO and CNRs, with magnetic CoFe2O4(CFO) nanoparticles uniformly dispersed throughout.
This hierarchical architecture exhibits superior impedance matching and attenuation capabilities. The optimized sample achieves a minimum reflection loss (RLmin) of -46.5 dB at a thickness of 3.3 mm. Furthermore, an ultrabroad effective absorption bandwidth (EAB) of 6.32 GHz (covering 11.68–18 GHz) is realized at a matching thickness of 3.9 mm.

Notably, the aerogel possesses an ultralow average density of 0.056 g/cm³. These findings suggest that the CFO/rGO/CNR composite is a promising candidate for next-generation, lightweight, and broadband EMW absorption applications.
