An ultralight Ni-MOF-rGO aerogel which possess the merits of not only broad bandwidth and strong absorption but also lightweight thin matching thickness is fabricated through a hydrothermal treatment, freeze-drying, annealing procedure. The Ni@C microspheres are dispersed randomly evenly on graphene oxide (GO) nanosheets, can be proved SEM TEM results. electromagnetic parameters composite adjusted by changing mass ratio MOF GO to endow material with both good impedance superior wave performances. Consequently, resulting shows outstanding microwave performance, achieves (−51.19 dB) effective (6.32 GHz) 1.9 mm while filling content 2 wt %. In addition, multiple loss mechanisms illustrated, including conduction loss, dipolar polarization, interfacial magnetic resonance, eddy current loss. word, extraordinary performance ascribed synergistic effects unique layered structure hollow core–shell microsphere. This work demonstrates that excellent promising strategy for application.

Abstract To reduce electromagnetic interference and noise pollution within communication base stations servers, it is necessary for wave absorption (EWA) materials to transition from coating multifunctional devices. Up now, the stable effective integration of multiple functions into one material by a simple method has remained large challenge. Herein, foam‐type microwave device assembled with multicomponent organic matter graphite powder synthesized universal combination process. Melamine phenolic aldehyde amine work as skeleton cementing compound, respectively, in which embedded compound interconnected mesoscopic 3D electric conductive heat network. Interestingly, prepared flexible graphite/melamine foam (CMF) delivers great EWA performance, bandwidth 9.8 GHz, ultrathin thickness 2.60 mm, strong reflection loss −41.7 dB. Moreover, CMF possesses porosity flexibility, endowing sound ability. The unique its EWA, conduction, absorption, mechanical robustness, well cost‐effective scalable manufacturing. These attributes make promising widely used stations, chips protection.
