Abstract
Electromagnetic (EM) signal safety and wave pollution have become ignored problems in the contemporary information era. Graphene-based materials are the most promising candidates for solving these two issues owing to their unique structural features and excellent EM properties. Designing ultrathin graphene-based materials with controllable multi-scale structures and outstanding characters can effectively improve the EM shielding parameters. In this review, the latest advances of multi-scale design strategies and application of graphene-based materials in high-performance EM shielding are summarized systematically. The mechanism of EM shielding and key influence factors are firstly discussed in detail. Then, the advantages and multi-scale structures majorization of graphene for EM shielding fields are outlined, including defect, doping and densifying. Thirdly, various kinds of micro/macroscale graphene-based materials are reviewed and compared, such as pure graphene films, foams, composites and multi-functional graphene materials, meanwhile the relationship between the structures of graphene and the value of EM shielding is in-depth analysis. Finally, the present challenges and future prospects in the field of graphene-based EM shielding applications are predicated. This review would provide new ideas and directions for high-performance graphene-based EM shielding.
期刊介绍：
The journal Carbon is an international multidisciplinary forum for communicating scientific advances in the field of carbon materials. It reports new findings related to the formation, structure, properties, behaviors, and technological applications of carbons. Carbons are a broad class of ordered or disordered solid phases composed primarily of elemental carbon, including but not limited to carbon black, carbon fibers and filaments, carbon nanotubes, diamond and diamond-like carbon, fullerenes, glassy carbon, graphite, graphene, graphene-oxide, porous carbons, pyrolytic carbon, and other sp2 and non-sp2 hybridized carbon systems. Carbon is the companion title to the open access journal Carbon Trends. Relevant application areas for carbon materials include biology and medicine, catalysis, electronic, optoelectronic, spintronic, high-frequency, and photonic devices, energy storage and conversion systems, environmental applications and water treatment, smart materials and systems, and structural and thermal applications.
