- Abstract
Nowadays, designing and fabricating electromagnetic (EM) wave absorbers with lightweight and strong reflection loss (RL) is still urgent. Herein, rGO/CoFe2O4 composite combined with magnetic CoFe2O4 nanorods and reduced graphene oxide (rGO) was fabricated via molten salt method in combination with a simple etching route. The EM absorption ability of rGO/CoFe2O4 nanorods composite can be regulated by changing the rGO addition amount. Particularly, the absorber for rGO/CoFe2O4 nanorods composite with the rGO addition amount of 70 mg (S-70) displays favorable EM wave absorption properties. The optimal RL value is − 56.3 dB at the frequency of 16.9 GHz, when the corresponding thickness is 1.4 mm. The effective absorption bandwidth (EAB, RL < − 10 dB) is 4.3 GHz, when the thickness is 1.6 mm. Consequently, the rGO/CoFe2O4 nanorods composite is a potential candidate for microwave absorbing materials.
