摘要: Abstract High-performance conductive films with electromagnetic interference (EMI) shielding, electrothermal, and photothermal properties are highly promising for the development of wearable devices, artificial intelligence, medical care, etc. However, designing such a film flexibility toughness remains challenge. Here, flexible multi-responsive composite EMI shielding is proposed by coating large-area electrospun carbon nanofiber (CNFFs) silicone an alternating multilayer structure (AMS). The optimal AMS presents superior (the effectiveness can reach ~ 100 dB low thickness 0.6 mm). Moreover, ultrafast electrothermal response gratifyingly performances also achieved, which guarantee normal functioning in cold conditions. Furthermore, outstanding be still maintained even after 1000 continuous bending cycles, without worsening performances. Such attributed to high electrical conductivity, large specific surface area nanofibers (CNFs), strong interface bonding strength, as well structure. Considering extraordinary performance facile preparation method, show tremendous potential large-scale applications advanced protection materials.
