Abstract Searching for advanced microwave absorption (MA) nanomaterials is one of the most feasible ways to address increasing electromagnetic pollution in both military and civil fields. To this end, graphene MXene have won widespread attention as main representatives due their remarkable structures properties. The common features such large aspect ratio, active chemical surface, varieties synthesis processes endow with unique superiorities developing high‐efficiency MA structures,...
Graphene is highly desirable as an electromagnetic wave (EM) absorber because of its large interface, high dielectric loss, and low density. Nevertheless, the conductive parameters pure graphene are too to meet requirement impedance match, which results in strong reflection weak absorption. In this paper, we report a facile solvothermal route synthesize reduced oxide (RGO) nanosheets combined with surface-modified γ-Fe2O3 colloidal nanoparticle clusters. The obtained two-dimensional hybrids...
Abstract Despite considerable efforts to tune the morphology and composition from macroscopic level nanoscale of electromagnetic wave‐absorbing materials (EWMs), achieving strong wide‐bandwidth absorption under a temperature‐variant environment remains extremely difficult due temperature‐sensitive electromagnetic‐absorbing mechanisms that involve dipole polarization conductive loss. Here, by integrating highly carbon nanotubes (CNTs) networks temperature‐stable silicon nitride (Si 3 N 4 )...
Considering the widespread presence of electromagnetic interferences (EMI), it is necessary to develop new wave (EM) absorbing materials with low reflection coefficient and large operating frequency band. The well-known EM have a microstructure combining permittivity phase high electrical conductivity phase.
