Abstract
(CSZF) not only meets impedance matching but also improves electromagnetic energy loss, a result of the unique microstructure. CSZF@C-1 exhibited a considerable reflection loss (RL) of -53.5 dB and an effective absorption bandwidth (EAB) of up to 6.56 GHz, the thickness is only 2.94 mm. Meanwhile, the epoxy resin coating of CSZF@C-1 substantially increases the corrosion resistance of the metal substrate owing to carbon encapsulation. This study presents new ideas for designing efficient multifunctional nanocomposites with high microwave absorption and corrosion resistance.
