Synthesis and characterization of nanosized urchin-like α-Fe2O3 and Fe3O4: Microwave electromagnetic and absorbing properties

Flowerlike iron oxide nanostructures and their application in microwave absorption

“…Besides, iron-based materials such as c-Fe 2 O 3 , and Fe 3 O 4 are recognized as promising materials for microwave applications because of their relative high magnetization and antioxidation properties in air. Various iron oxides or iron composites with different morphologies such as rods, wires, tubes, flakes, urchins and dendrites have been successfully reported with their application as electromagnetic wave absorber [7][8][9][10][11][12].…”

Synthesis and characterization of hybrid conducting composites based on polyaniline/magnetite fillers with improved microwave absorption properties

“…Over the last decade, many researches focused on a new type of hybrid material based on polymers-matrix composites containing dielectric or/and magnetic fillers [18]. Combination of PANI with other organic or inorganic materials provides new materials with tailored properties, suitable for various electrical and electromagnetic applications in aeronautic or aerospace areas and to avoid electromagnetic pollution arising from various electronic devices operating in microwave frequency range [19,20]. The dispersion of polyaniline and magnetite fillers in an insulating polymer matrix (thermoplastic or thermosetting) produces different composites that can absorb and reflect electromagnetic radiation by changing its conductivity, its dielectric constant and its magnetic permeability.…”

Design of mesostructured γ-Fe2O3/carbon nanocomposites for electromagnetic wave absorption applications

“…Recently, the development of carbon-based materials with designed pore architecture may provide the possibility of a promising candidate for microwave absorbers, especially in the cases of light weight and harsh environment [3][4][5][6][7]. Their unique structure and properties can be utilized to overcome the shortcomings of conventional microwave absorbing materials [8][9][10][11][12][13]. Ordered mesoporous carbon CMK-3 embedded in mesoporous silica SBA-15 are built for electromagnetic interference shielding materials in the X band [14].…”
