Ultra-thin metal composites for electromagnetic interference shielding

Electromagnetic (EM) radiation pollution is increasing attention due to the popularization of electronic equipment. In recent years, various nanomaterials have been widely designed and developed for enhancement their EM interference shielding effectiveness (EMI SE). However, large amounts reported reviews focus on carbon materials transition metal carbides (e.g., MXenes), while applications nanocomposites in are still suffering from insufficient systematic analysis. Therefore, this paper provides comprehensive information material selection, whole structural design, engineering preparation schemes latest cutting-edge techniques elaborate (thickness ?1 mm) EMI SE. We firstly describe principle SE structure design. Then we also investigate selection based metals such as silver, copper, nickel, combinations with or other materials. Finally, compare strengths weaknesses identify state-of-the-art methodologies.
