外文摘要：Due to the increase in electromagnetic wave radiation pollution, there is a critical need for high-performance electromagnetic wave absorption (EWA) materials to mitigate electronic emissions from electronics and electro-mechanical devices. However, manufacturing EWA materials with strong attenuation capabilities and thermal characteristics remains a challenging problem, limiting their further application in daily life. This research demonstrates the rational fabrication of a novel magnetic reduced graphene oxide/cellulose nanofiber (M-rGO/CNF) hybrid aerogel with magneto-conduction networks for EWA applications. The M-rGO/CNF aerogel provided outstanding structural integrity, excellent magnetic permeability, and remarkable EWA capabilities induced by the synergistic impact of impedance matching features and magnetic loss capability. Our study provides a new approach to fabricating highly stable aerogels with excellent mechanical properties, thermal insulation properties, and EWA absorption performance.
