Antimicrobial properties of electromagnetic shielding materials

Electromagnetic shielding materials are highly antimicrobial. According to the query relevant public information, electromagnetic shielding (EMI) is vital in the field of portable electronic devices, wireless communications, aerospace, military and medical equipment, is an indispensable means to ensure the normal operation of equipment. With the development of smart lighting and wearable devices, there is an urgent need for materials that are small in size, light in weight, flexible, hydrophobic, and have good EMI performance, but current EMI materials are mostly metal-based, heavy, and have poor toughness. In response to this need, researchers have developed numerous functional conductive nanocomposites or components, such as materials based on carbon nanotubes (CNTs), graphene, transition metal carbides (MXene), and metal nanofibers. Among them, the introduction of microporous structures in EMI materials, which can effectively improve the shielding efficiency (SE) by increasing the number of reflections of incident electromagnetic waves, is increasingly favored, and the normalized specific SE (SSE) value of such materials.
