A solution-processed Ag@ZnO core–shell nanowire network for stretchable transparent electromagnetic interference shielding application

Abstract

Metal nanowire (NW) networks intrinsically have good optical transparency, electrical conductivity and mechanical flexibility, and thus are widely used as electrodes of flexible electronics and electromagnetic interference (EMI) shielding materials....

Aligned Silver Nanowires Wrapped in Graphene as a Transparent Electrode for Electromagnetic Interference Shielding Applications

“…Furthermore, a comparison accentuates the superior optoelectronic capabilities of the G–ASNWs against other counterparts such as Ag/oxide NWs, Ag/Au NWs, and Ag/graphene hybrid films (Figure d). The deduced FoMs for our G–ASNWs range between 500 and 600, outpacing the performance metrics of the current core–shell MNN TCs. − ,− …”

“…The ideal configuration, metal/protective-layer core–shell nanowire (NW) networks, promises performance boosts without compromising transmittance. Even though protective materials such as TiO 2 , ZnO, and Au have been trialed via methodologies like electrodeposition and replacement reactions, ,− such protectants often form nanostructures during their growth, underscoring the pressing need to further investigate metal/graphene core–shell networks. However, the precise deposition of two-dimensional graphene sheets onto one-dimensional metal NWs continues to be a formidable challenge and remains underexplored.…”

(d) Sheet resistance against optical transmittance for G–ASNWs and other benchmark TCs such as Ag/graphene NWs, Cu/graphene NWs, , Ag/Au NWs, and AgNWs/graphene hybrid films, − and Ag/oxide NWs. − , …”

Flexible Transparent Conductive Films of Ag/Cr2O3 Core–Shell Nanowires as Electrodes for Electroluminescent Devices and Heaters

“…Singh et al introduced a two-step synthesis method based on electrodeposition to synthesize Ag-(Ni–O) core–shell nanowires with a total diameter of 200 nm . Yan and Wang can coat ZnO on Ag NW network by electrodeposition process to improve the conductivity and stability of Ag NW network without affecting the flexibility and light transmittance . However, the electrodeposition process may fracture, warp, and deform the coating, affecting the performance of the coating; the electrolyte used in this method is toxic and harmful, and the waste liquid pollutes the environment and is not easy to dispose of.…”

“…28 Yan and Wang can coat ZnO on Ag NW network by electrodeposition process to improve the conductivity and stability of Ag NW network without affecting the flexibility and light transmittance. 29 However, the electrodeposition process may fracture, warp, and deform the coating, affecting the performance of the coating; the electrolyte used in this method is toxic and harmful, and the waste liquid pollutes the environment and is not easy to dispose of. Recently, our group prepared the SnO 2 30 and NiO 31 shells on the surface of Ag NWs by using an all-solution process.…”
