Bilayered Distribution of Ag and Fe3O4 in Electrospun TPU Films for Low-Reflection Electromagnetic Interference Shielding and Multiple Thermal Management Functionalities

“…It is worth noting that the average SE A value of all the samples accounts for more than 80% of the average SE T value (Figure S10). These results prove that the lower layer contributes to the total shielding effectiveness, while the upper layer could improve the SE A values …”

“…These results prove that the lower layer contributes to the total shielding effectiveness, while the upper layer could improve the SE A values. 47 To intuitively access the shielding mechanism of bilayered composite films, the absorption coefficient (A) and reflection coefficient (R) values of the composite films against the whole X-band are shown in Figure S11, representing the ability to absorb and reflect EM waves, respectively. It is also found that the R and A values of TPAFx Upper and TPAFx Lower show a huge difference.…”

Hollow Metal–Organic Framework/MXene/Nanocellulose Composite Films for Giga/Terahertz Electromagnetic Shielding and Photothermal Conversion

“…S8). After carbonization at high temperature, the two new peaks remain at 560 and 650 cm −1 , corresponding to Co [ 38 ]. These characteristic peaks were also observed in the FTIR spectrum of HMN composite films.…”

Flexible Embedded Metal Meshes by Sputter-Free Crack Lithography for Transparent Electrodes and Electromagnetic Interference Shielding

“…1−7 To address EMI shielding needs, a wide variety of materials have been studied including metal films, 1,3,8−11 metal meshes, 12−16 metal nanowires, 17−19 graphene, 20 carbon nanotubes, 21,22 and MXenes. 23 There is also growing interest in hybrid structures, 24−26 such as conductive oxide/metal, 27−29 MXene/metal, 30,31 and metal/graphene. 32,33 Furthermore, many modern optoelectronic devices, such as light-emitting diodes, car windows, displays, touchscreens, solar cells, and optical communication systems, need materials that are both visibly transparent and capable of blocking RF signals.…”
