Abstract Electromagnetic (EM) functional materials play an increasingly important role in solving EM wave pollution both modern military and civil fields. Graphene‐based are the most promising candidates applications of shielding absorption owing to their remarkable structures enhanced properties. Designing graphene‐based with elaborately controlled microstructures optimized properties can effectively improve energy attenuation conversion. Herein, study begins mechanism, multiscale design strategies outlined, including molecular‐scale, micro/nanoscale structure, macroscale integration assembly strategies. Applications fields reviewed, focusing on latest advances assemblies such as films, fabrics, composites. Finally, current challenges future directions this fast‐growing field predicted.

Developing ultrabroad radar-infrared compatible stealth materials has turned into a research hotspot, which is still problem to be solved. Herein, the copper sulfide wrapped by reduced graphene oxide obtain three-dimensional (3D) porous network composite aerogels (CuS@rGO) were synthesized via thermal reduction ways (hydrothermal, ascorbic acid reduction) and freeze-drying strategy. It was discovered that phase components (rGO CuS phases) micro/nano structure (microporous nanosheet) well-modified modulating additive amounts of changing ways, resulted in variation pore structure, defects, complex permittivity, microwave absorption, radar cross section (RCS) value infrared (IR) emissivity. Notably, obtained CuS@rGO with single dielectric loss type can achieve an bandwidth 8.44 GHz at 2.8 mm low filler content 6 wt% hydrothermal method. Besides, aerogel realizes minimum reflection (RLmin) - 60.3 dB lower 2 wt%. The RCS reach 53.3 m2, effectively reduces probability target being detected detector. Furthermore, laminated architecture multicomponent endowed insulation IR versatility. Thus, this work offers facile method design develop rGO-based absorbers radar-IR stealth.

Metal-organic frameworks (MOFs) are used to directly initiate the gelation of graphene oxide (GO), producing MOF/rGO aerogels. The ultralight magnetic and dielectric aerogels show remarkable microwave absorption performance with ultralow filling contents. development a convenient methodology for synthesizing hierarchically porous comprising metal-organic (GO) building blocks that exhibit an density uniformly distributed MOFs on GO sheets is important various applications. Herein, we report facile route MOF/reduced (rGO) based GO, which initiated using MOF crystals. Free metal ions exposed surface MIL-88A nanorods act as linkers bind nanosheets three-dimensional network via metal-oxygen covalent or electrostatic interactions.
