Multifunctional magnetic graphene/nano cellulose hybrid aerogel with excellent electromagnetic wave absorption and thermal insulating performances
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.
期刊介绍：
DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices.
The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
