Emi Se

The structural design of thin films is attracting attention in academia and industry in attempts to improve electromagnetic interference shielding effectiveness (EMI SE). In this study, MXene/chitosan/silver nanowire (AgNW) sandwich films, in which the AgNW core layer was bordered by two MXene/chitosan layers, were fabricated by vacuum-assisted filtration. Because of the interconnected AgNWs in the core layer and the aligned MXene sheets in the MXene/chitosan layers, the electrical conductivity of the sandwich film reached 11,459.1 S/m. Consequently, the sandwich film exhibited an SE value of 82.3 dB. What is more, when both the AgNW and MXene contents were 33.3%, the sandwich film’s EMI SE divided by its thickness was 26,167 dB/cm, which was much superior to the values reported for inorganic hybrid composites and polymer composites filled with hybrid fillers. Such a simple approach was proved to be an effective way for further structure design of thin films in EMI shielding field.

A free-standing graphene oxide/Ag nanowire film with a dense sandwich-like structure was fabricated via vacuum-assisted self-assembly. The EMI SE is up to 62 dB when the thickness is merely 8 μm in 8–40 GHz. The corresponding specific SE (EMI SE/t) is up to 77 500 dB cm−1.

Commercial Carbon

Synthesized silver nanowire/polystyrene nanocomposites showed superior electrical properties to commercial carbon nanotube/polystyrene nanocomposites at high filler loadings. This was ascribed to the higher metallic nature of silver nanowires.
