“…The D-band (1350 cm −1 ) is a Raman feature induced by defects, and the G-band (1580 cm −1 ) corresponds to the E 2g vibrational mode in the ideal graphite lattice (detail see Note S6, Supporting Information). [30,[49][50][51] The I D /I G ratio serves as an indicator to evaluate the degree of graphitization of the material (Figure 3j). The calculated values show a rapid decrease after eliminating interference from other subpeaks, indicating that the degree of graphitization increases rapidly with an increase in pyrolysis temperature.…”

High‐performance electromagnetic wave (EMW) absorbers are essential for addressing electromagnetic pollution and military security. However, challenges remain in realizing cost‐effectiveness and modulating absorbing properties. In this study, heterogeneous Co/nanoporous carbon (NPC) nano‐islands are prepared by efficient method co‐precipitation combined with in situ pyrolysis. The multi‐regulation strategy of morphology, graphitization, and defect density is achieved by modulating the pyrolysis temperature. Adjusting the pyrolysis temperature can effectively balance the conductivity and defect density, optimizing the impedance matching and enhancing the attenuation. Furthermore, it facilitates obtaining the appropriate shape and size of Co magnetic nanoparticles (Co‐MNPs), triggering strong surface plasmon resonance. This resonance, in turn, bolsters the synergy of dielectric and magnetic loss. The incorporation of porous nanostructures not only optimizes impedance matching and enhances multiple reflections but also improves interfacial polarization. Additionally, the presence of enriched defects and heteroatom doping significantly enhances dipole polarization. Notably, the absorber exhibits an impressive minimum reflection loss (RLmin) of −73.87 dB and a maximum effective absorption bandwidth (EABmax) of 6.64 GHz. The combination of efficient fabrication methods, a performance regulation strategy through pyrolysis temperature modulation, and radar cross section (RCS) simulation provides a high‐performance EMW absorber and can pave the way for large‐scale applications.

“…Various matters (silica and metal oxides, monomers-precursors of synthetic polymers) have been used to synthesise aerogels; for the detailed information see Aerogels Handbook, 2011. In addition to low thermal conductivity, aerogels are suggested to be used for oil/water separation (Wang X. et al, 2020;Zou, Peng, Fu, Zhang, & Li, 2015), drug release (Follmann et al, 2020;Lim et al, 2020), energy storage (Lin et al, 2018;Zhou et al, 2018), for adsorption (Maleki, Whitmore, & Hüsing, 2018) and as catalyst supports Zhang et al, 2017). At the beginning of the 21 st century, a new class of aerogels was made: they are based on natural polymers such as polysaccharides and proteins (Zhao, Malfait, Guerrero-Alburquerque, Koebel, & Nyström, 2018;Budtova et al, 2020).…”

Graphene-based aerogels (GA) have a high potential in the biomedical engineering field due to high mechanical strength, biocompatibility, high porosity, and adsorption capacity. Thanks to this, they can be used as scaffolds in bone tissue engineering, wound healing, drug delivery and nerve tissue engineering. In this review, a current state of knowledge of graphene (Gn) and graphene oxide (GO) aerogels and their composites used in biomedical application is described in detail. A special focus is paid first on the methods of obtaining highly porous materials by visualizing the precursors and describing main methods of Gn and GO aerogel synthesis. The impact of synthesis parameters onto aerogel microstructure and porosity is discussed according to current knowledge. Subsequent sections deal with aerogels intended to address specific therapeutic demands. Here we discuss the recent methods used to improve Gn and GO aerogels biocompatibility. We explore the various types of GA reported to date and how their architecture impacts their ultimate ability to mimic natural tissue environment. On this basis, we summarized the research status of graphene-based aerogels and put forward the challenges and outlook of graphene-based aerogels dedicated to biomedical usage especially by formation of joints with biocompatible metals.
