A New Broadband and Strong Absorption Performance FeCO(3)/RGO Microwave Absorption Nanocomposites

A novel composite of FeCO(3) nanoparticles, which are wrapped with reduced graphene oxide (RGO), is fabricated using a facile one-spot solvothermal method. The composite consists of a substrate of RGO and FeCO(3) nanoparticles that are embedded in the RGO layers. The experimental results for the FeC...

description A novel composite of FeCO(3) nanoparticles, which are wrapped with reduced graphene oxide (RGO), is fabricated using a facile one-spot solvothermal method. The composite consists of a substrate of RGO and FeCO(3) nanoparticles that are embedded in the RGO layers. The experimental results for the FeCO(3)/RGO composite reveal a minimum refection loss (−44.5 dB) at 11.9 GHz when the thickness reaches 2.4 mm. The effective bandwidth is 7.9 GHz between 10.1 and 18 GHz when the refection loss was below −10 dB. Compared to GO and RGO, this type of composite shows better microwave absorption thanks to improved impedance matching. Overall, this thin and lightweight FeCO(3)/RGO composite is a promising candidate for absorbers that require both strong and broad absorption.
