The high-efficiency utilization of two-dimensional (2D) graphene layers for developing durable multifunctional electromagnetic wave (EMW) absorbing aerogels is highly demanded yet remains challenging. Here, renewable, low-density, high-strength, and large-aspect-ratio ceramic silicon dioxide (SiO2) nanofibers were efficiently prepared to assist in the preparation ultralight robust, elastic, hydrophobic using facile, scalable freeze-drying followed by a carbonization approach. prevent agglomeration enhance interfacial interactions, significantly promoting mechanical strength. In addition high conduction loss capability derived from interconnected network, polarization abundant heterogeneous interfaces accomplished three-dimensional (3D) hybrid aerogels. thus showcase excellent EMW absorption performance, involving minimum reflection −74.5 dB at 1.8 mm an effective bandwidth 5.7 GHz, comparable those best absorbers. Furthermore, integration one-dimensional SiO2 2D into 3D enables remarkable photothermal antibacterial, oil absorption, thermal insulation performances. This work provides type ceramic/graphene aerogel with accomplishing high-performance applications.

To solve the urgent issue of electromagnetic (EM) wave radiation pollution and promote resource utilisation red mud (RM, a solid waste), Fe/C/ceramic composite EM wave-absorbing materials were constructed by recycling RM with raw coal (RC) through simple mechanical mixing then carbothermal reduction between Fe2O3 in carbon component RC. It was found that calcined temperature 900 °C can be considered optimal formation for Fe. In addition, tuneable absorption performance could attained regulating mass ratio RC to (denoted as MRC:MRM). When MRC:MRM value reaches 0.4:1 0.5:1, composites exhibit more favourable performance. The showed minimum reflection loss (RLmin) −41.6 dB, accompanied an effective bandwidth (EAB) 3.2 GHz when simulating thickness 2 mm. 0.5:1 possessed maximum EAB 4.2 RLmin −25.3 dB at 1.5 satisfactory profits from good impedance matching strong intrinsic attenuation capability. former attributed regulatable parameters multicomponent system; latter is mainly credited dielectric arising medium graphitised carbon, highly crystalline Fe, plentiful defects interfaces composites. This work not only provides valid path realise economical preparation microwave absorbents but also achieves rational disposal RM.
