![]() 1–4 According to absorption mechanism, 5 traditional microwave absorption materials can classified into magnetic loss materials such as ferrite 6 and magnetic metal powders, 7 and dielectric loss materials such as metal oxides, 8 carbon materials 9 and conduction polymers. So over the past few years, tremendous research efforts have been focused on the fabrication of microwave absorption materials. Introduction More and more microwave radiation is generated through the development of science and technology, causing pollution to the environment and cause harm to human beings. These results demonstrate a facile method to prepare a highly efficient microwave absorption material with special microstructure. For the Fe 3O composite, a maximum R L value of −48.6 dB can be obtained at 13.9 GHz with a thickness of 3.0 mm, and the absorption bandwidth with R L below −10 dB is 7.1 GHz from 10.9 GHz to 18 GHz. ![]() The thickness corresponding to optimum reflection loss ( R L) decreases as the weight ratio of RGO increases. The addition of RGO not only effectively reduces the agglomeration of Fe 3O but also has a great effect on impedance matching and dielectric loss, resulting in enhanced microwave absorption abilities. ![]() The microwave absorption properties of the samples can be adjusted by the weight ratio of RGO. ![]() Porous Fe 3O core/shell nanorods decorated with reduced graphene oxide (RGO) were fabricated through a facile one-pot method. ![]()
