There are different requirements for the EMI SE of materials in different application domains. Here, we divide it into five levels. With the increase of the level, the EMI SE increases, as shown in Table 4 [133]. EM shielding materials play an active role in various fields. In the aerospace field, EM shielding materials can prevent outside signal interference and maintain accurate equipment operation. Resistance to high temperatures, abrasion resistance and fast heat dissipation are also key factors. In the military sector, stealth armaments require the support of EM shielding materials. In industrial applications, the regular operation of many devices requires shielding from external EM interference. In some conditions, adapting to different environments such as high temperatures, strong winds, corrosion and extreme cold is also significant. In medical applications, EM interference protection equipment is crucial to the health of medical care and patients. In all aspects of daily life, EM shielding materials help to keep us safe from EM pollution and protect the physical and mental health of people and other animals. In addition to EMI SE, ultra-thin metal composites often need to have a number of other characteristics. For example, light transmission is required for internal viewing, water and pressure resistance for deep-sea devices, flexibility and breathability for wearable devices, etc. Whether in research or commerce, EM interference shielding materials have an enormous scope and market potential. Research into EM interference shielding materials is a subject of great interest.

N2 - 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 the enhancement of their EM interference shielding effectiveness (EMI SE). However, large amounts of reported reviews focus on carbon materials and transition metal carbides (e.g., MXenes), while the applications of metal nanocomposites in EM interference shielding are still suffering from the insufficient systematic analysis. Therefore, this paper provides comprehensive information on material selection, whole structural design, engineering preparation schemes and the latest cutting-edge techniques to elaborate the metal nanocomposites (thickness ≤1 mm) for EMI SE. We firstly describe the principle of EMI SE and structure design. Then we also investigate the material selection based on metals such as silver, copper, nickel, and their combinations with carbon materials or other materials. Finally, we compare the strengths and weaknesses of various preparation schemes and identify the state-of-the-art cutting-edge methodologies.
