Transparent, conductive and flexible MXene grid/silver nanowire hierarchical films for high-performance electromagnetic interference shielding

Abstract

The flexible and conductive MXene grid/silver nanowire hierarchical film exhibits both high optical transmittance and excellent electromagnetic interference shielding efficiency.

Robust, transparent, and conductive AgNW/MXene composite polyurethane self-healing film for electromagnetic interference shielding

“…27 Additionally, Jin et al exploited a hierarchical MXene grid/AgNW film, achieving a high transmittance of 81% and an outstanding EMI SE of 24.6 dB. 28 These results clearly show that the preparation of transparent conductive films with AgNW and MXene has made decent progress. Despite the many advantages of polymer-based TCFs, the inevitable damage to the polymer during operation is the greatest obstacle to their further application.…”

Multifunctional MXene-based composite films with simultaneous terahertz/gigahertz wave shielding performance for future 6G communication

“…Therefore, EMI shielding materials that could block the interference of both GHz and THz waves are critical. However, most reported EMI shielding materials such as carbon-based materials (carbon bers and carbon nanotubes), metals/metallic compounds (copper and aluminum) and conductive polymers (PANI and polypyrrole) only show shielding performance in a single frequency band, [16][17][18][19][20] due to their limited responses to electromagnetic waves, [21][22][23][24] and such a THz/GHz integrated shielding material has rarely been reported yet. [25][26][27] Therefore, the development of EMI shielding materials with simultaneous GHz/THz shielding effectiveness remains a big challenge.…”

Flexible, Stretchable, and Transparent MXene Nanosheet/Thermoplastic Polyurethane Films for Multifunctional Heating and Electromagnetic Interference Shielding

“…1−3 On the other hand, to cope with the increasingly serious EMI pollution, higher requirements for flexibility, transparency, and shielding efficiency are put forward for EMI shielding materials. 4,5 To date, conventional transparent 3indium tin oxide cannot meet the potential applications of flexible electronics due to its intrinsic brittleness. 6,7 Thus, various transparent conductive materials as alternatives, including carbon nanotubes, 8 metallic nanowires, 9−11 metal meshes, 12,13 and graphene, 14 have been developed.…”

“…Transparent conductive films (TCF) play an essential role as a component in various optoelectronic devices, including smart windows, touch panels, and displays. It is also widely used in transparent heating and electromagnetic interference (EMI) shielding applications. − On the other hand, to cope with the increasingly serious EMI pollution, higher requirements for flexibility, transparency, and shielding efficiency are put forward for EMI shielding materials. , To date, conventional transparent 3indium tin oxide cannot meet the potential applications of flexible electronics due to its intrinsic brittleness. , Thus, various transparent conductive materials as alternatives, including carbon nanotubes, metallic nanowires, − metal meshes, , and graphene, have been developed. Despite the encouraging advances, the search for effective transparent EMI shielding materials is still challenging to satisfy both light transmittance and high EMI shielding performance.…”
