“…Sheet resistance versus optical transmittance at 550 nm for rGO/Ag NW films and previous reported Ag NW-based transparent conductive films are plotted in Fig. 3f and Table 1 [9,17,19,20,[35][36][37][38][39][40][41]. The rGO/Ag NW films combine the merits of high transmittance and low sheet resistance.…”

Silver nanowire (Ag NW) has been considered as the promising building block for the fabrication of transparent electromagnetic interference (EMI) shielding films. However, the practical application of Ag NW-based EMI shielding films has been restricted due to the unsatisfactory stability of Ag NW. Herein, we proposed a reduced graphene oxide (rGO) decorated Ag NW film, which realizes a seamless integration of optical transparency, highly efficient EMI shielding, reliable durability and stability. The Ag NW constructs a highly transparent and conductive network, and the rGO provides additional conductive path, showing a superior EMI shielding effectiveness (SE) of 33.62 dB at transmittance of 81.9%. In addition, the top rGO layer enables the hybrid film with reliable durability and chemical stability, which can maintain 96% and 90% EMI SE after 1000 times bending cycles at radius of 2 mm and exposure in air for 80 days. Furthermore, the rGO/Ag NW films also possess fast thermal response and heating stability, making them highly applicable in wearable devices. The synergy of Ag NW and rGO grants the hybrid EMI shielding film multiple desired functions and meanwhile overcomes the shortcomings of Ag NW. This work provides a reference for preparing multifunctional integrated transparent EMI shielding film.

“…graphene or carbon nanotubes (CNT); which are reported to increase the stability to mechanical stress and oxidation, in addition to be better heat conductors). [104][105][106] Coating the Ag NW network with a conductive polymer was reported to increase the thermal properties of a heater (but not the resistivity). 107,108 A valid alternative to silver to prepare similar structures is copper, 109 which has a lower price but it is also a worse conductor.…”

“…88 102,110 However, most of the studies rely only on the -experimentally obtained -relationship between the applied voltage and the corresponding reached temperature to control the heating level of the device. 82,[103][104][105]110,121,133 However, this method does not take into account the inter-subject variability of heat transfer conditions and provoked sensations, an issue of primary importance for the healthcare market. For example, changes in blood flow can cause changes in skin temperature differently from person to person.…”

“…[ 11 ] For this application, optical transparency and portability, flexibility, fast response, breathability, and uniform heating are also important. [ 6,12 ] Various types of conducting polymers, [ 4 ] semiconductor oxides, [ 13 ] their composites, and most recently carbon‐based nanomaterials [ 14,15 ] have been proposed for flexible thermotherapy patches due to their flexibility, transparency, and good electrical conductivity. However, most of the heater surfaces are not very promising during different types of mechanical strains that occur during bending and folding.…”

Performance Comparison of Fast, Transparent, and Biotic Heaters Based on Leaf Skeletons

Bioinspired, highly flexible, fast, and biodegradable heaters are fabricated based on Ag nanowires and leaf skeletons of different plant species. The leaf skeletons act as transparent substrates with a high surface‐area‐to‐volume ratio and allow a uniform dispersion of the Ag nanowires through the surface. Ag nanowires adhered to the leaf skeletons display very good transmittance (up to ≈87%) and mechanical (flexibility) properties (curvature values >800 m−1) without any post‐treatment. The flexible leaf skeleton‐based heaters reach high temperatures very quickly, with very low voltages (<4 V). The performance of the bioinspired heater surface is dependent on the types of fractal structures at the microscale. The morphology of the leaf skeletons is studied in detail and is corelated with the transmittance, flexibility, and sheet resistances. Bioinspired heater surfaces based on different leaf skeletons are compared based on their multiscale morphology, and the different heating performance parameters are screened. Based on the study conducted, insights on the best‐performing biotic design for the fabrication of the heaters that are useful in practical wearable, medical, or industrial heating applications are provided.
