Study on microwave absorbing properties of carbonyl–iron composite coating based on PVC and Al sheet

Flowerlike iron oxide nanostructures and their application in microwave absorption

“…In recent years, carbonyl irons were widely investigated as one of typical magnetic microwave absorbing materials [2][3][4]. However, the low density and absorption properties of the commercial carbonyl iron restrict its use in the applications.…”

Facile synthesis of hierarchical nanocomposites of aligned polyaniline nanorods on reduced graphene oxide nanosheets for microwave absorbing materials

“…[1][2][3] To prevent and restrain these hazards, the demands for developing electromagnetic wave absorbers with broader absorbing bandwidths and more effective absorption properties is ever urgent which has aroused the intense interest of researchers. 4,5 Graphene, a at monolayer of hexagonally arrayed sp 2bonded carbon atoms tightly packed into a two-dimensional (2D) honeycomb lattice, has attracted tremendous scientic attention due to its promise in the eld of microwave-absorbent materials. 6,7 Furthermore, reduced graphene oxide (RGO) coupled with clustered defects and functional groups has the properties of graphene while being easier to fabricate.…”

Preparation of SnO2-coated carbonyl iron flaky composites with enhanced microwave absorption properties

“…CI powder has traditionally been widely used as microwave-absorbing material due to its low cost, high magnetic losses and high specific saturated magnetization properties. However, low microwave permittivity value of monodispersed CI particles is an obvious disadvantage [1,2]. It has been reported that microwave absorption properties could be enhanced via the complementation of dielectric and magnetic loss [3][4][5].…”
