“…Furthermore, after 10,000 repeated cyclic bends, the EMI SE of the Fe 3 O 4 /graphene foam/PDMS composite was 29.4 dB. Wu et al [ 146 ] also synthesized 3D porous-network composites containing rGO and Fe 3 O 4 nanoparticles (rGO/Fe 3 O 4 ) using hydrothermal and freeze-drying processes ( Figure 5 ). The transmission electron microscopy (TEM) results indicated that Fe 3 O 4 nanoparticles were effectively deposited on the 3D porous network structure of rGO.…”

Graphene and its derivatives have been confirmed to be among the best fillers for rubber due to their excellent properties, such as high mechanical strength, improved interface interaction, and strain-induced crystallization capabilities. Graphene rubber materials can be widely used in tires, shoes, high-barrier conductive seals, electromagnetic shielding seals, shock absorbers, etc. In order to reduce the graphene loading and endow more desirable functions to rubber materials, graphene-based hybrid fillers are extensively employed, which can effectively enhance the performance of rubber composites. This review briefly summarizes the recent research on rubber composites with graphene-based hybrid fillers consisting of carbon black, silica, carbon nanotubes, metal oxide, and one-dimensional nanowires. The preparation methods, performance improvements, and applications of different graphene-based hybrid fillers/rubber composites have been investigated. This study also focuses on methods that can ensure the effectiveness of graphene hybrid fillers in reinforcing rubber composites. Furthermore, the enhanced mechanism of graphene- and graphene derivative-based hybrid fillers in rubber composites is investigated to provide a foundation for future studies.

“…Currently, foams and aerogels with porous network structure, high porosity, high specific surface area, such as melamine hybrid foam [ 26 ], chitosan-derived carbon aerogels [ 27 ], porous carbon@CuS [ 11 ], antimony tin oxide/rGO aerogels [ 28 ], cobalt ferrite/carbon nanotubes/waterborne polyurethane hybrid aerogels [ 29 ], Fe/Fe 2 O 3 @porous carbon composites [ 30 ], cellulose-chitosan framework/polyaniline hybrid aerogel [ 31 ], rGO/MWCNT-melamine composite [ 32 ], organic-inorganic hybrid aerogel [ 33 ], and rGO/Fe 3 O 4 [ 34 ], are commonly applied as radar-IR stealth materials. Although the reported carbon-based radar-IR compatible stealth materials can achieve MA performance and thermal/IR stealth, it is difficult to gain a wide EAB (> 8 GHz) and low IR emissivity (< 6.5) with a low filler content (< 5 wt%).…”

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

In contemporary times, radar and infrared‐compatible stealth materials have emerged as a pivotal domain of research globally, aimed at augmenting the survivability of military assets. However, current candidates generally exhibit subpar compatibility performance in elevated temperature environments due to the imbalanced interplay between the two spectral bands. In this work, a meticulously designed sandwich‐structure SiO2/C@SiC/SiO2 composite is proposed to cope with the challenge. The middle layer of C@SiC composites possesses excellent microwave absorption performance even at high temperatures. The outer layers of SiO2 aerogels serve not only to inhibit the infrared radiation intensity, but also reinforce the microwave absorption capacity by optimizing the impedance matching and reducing the heat transferred to the middle layer. Based on the numerical simulation outcomes, the thickness of each layer has been optimized to attain a harmonious balance between microwave absorption and infrared radiation properties. Ultimately, the sandwich structured SiO2/C@SiC/SiO2 composites demonstrate low RL (reflection loss) values (←5 dB) across nearly the entire X band (8–12 GHz), alongside minimal surface temperatures hovering ≈44 °C at an ambient temperature of 200 °C. The comprehensive investigation into impact patterns and underlying mechanisms offers invaluable insights to develop radar and infrared‐compatible stealth materials for high‐temperature applications, which can be applied as stealth coatings on the skin of high Mach number aircraft.
