“…The typical XRD diffraction peaks of AgNWs exhibited four characteristic peaks at 2 θ = 38.5°, 44.8°, 64.9°, and 77.8°, indexed to the successful synthesis of face‐centered cubic crystalline AgNWs. [ 23 ] For the ZIF‐8@AgNWs composites, except for the distinct diffraction peaks of AgNWs, the characteristic peaks of ZIF‐8 were also observed, further confirming the successful preparation of the ZIF‐8@AgNWs composites.…”

Due to the wider bandgap and low electron discharge capacity, the zeolitic imidazolate framework (ZIF‐8) shows low photocatalytic performance compared with conventional semiconductor materials. To enhance the photocatalytic activity of ZIF‐8, the ZIF‐8@AgNWs composite is synthesized via the in situ growth method using silver nanowires (AgNWs) as the photo‐enhanced material. The obtained ZIF‐8@AgNWs exhibit the fully encapsulated shell‐core structure of ZIF‐8‐AgNWs. The UV−vis diffuse reflectance spectroscopy (DRS) analysis shows that the addition of AgNWs leads to a significant increase in light absorption of the ZIF‐8@AgNWs composite, and the bandgap of the ZIF‐8@AgNWs is 2.9 eV, with a significant decrease compared to pure ZIF‐8 (4.96 eV). The ZIF‐8@AgNWs‐2 achieves the best photocatalytic activity for methylene blue (MB) degradation. Its degradation eﬃciency reaches 94%, and its apparent rate constant is 0.04371 min−1. Herein, a novel strategy for the MOF‐based photocatalytic materials with higher photocatalytic activity is provided.

“…They found a spherical-cubelinear morphology progression as the concentration of Na 2 S was increased [91]. Zhao et al regulated the morphology and size of AgNWs with ferric chloride (FeCl 3 ) as a mediation and nucleation agent and PVP as a capping agent to synthesize AgNWs with aspect ratio up to 570 (from 250 to 570) [110]. Rui et al investigated the effect of Cland Brin the polyol synthesis of high yield (>85%) and high aspect ratio (up to 2500) of AgNWs.…”

Silver nanowires (AgNWs) have a broad range of applications including nanoelectronics, energy conversion, health care, solar cells, touch screens, sensors and biosensors, wearable electronics, and drug delivery systems. As their characteristics depend strongly on their size and morphology, it is essential to find the optimal and most cost-effective synthesis method with precise control over the size and morphology of the wires. Various methods for AgNW synthesis have been reported along with process optimization and novel techniques to increase the yield and aspect ratios of synthesized AgNWs. The most promising processes for synthesis of AgNWs are wet chemical techniques, in which the polyol process is low cost and simple and provides high yield compared to other chemical methods. Reaction mechanism is one of the most important factors in strategies to control the process. Our purpose here is to provide an overview on the main findings regarding synthesis, preparation, and characterization of AgNWs. Recent efforts in the polyol synthesis of AgNWs are summarized with respect to product morphology and size, reaction conditions, and characterization techniques. The effect of essential factors such as reagent concentration and preparation, temperature, and reaction atmosphere that control the size, morphology, and yield of synthesized AgNWs is reviewed. Moreover, a review on the novel modified polyol process and reactor design such as continuous millifluidic and flow reactors to increase the yield of synthesized AgNWs on large scales is provided. The most recent proposed growth mechanisms and kinetics behind the polyol process are addressed. Finally, comparatively few available studies in green and sustainable development of 1D silver nanostructures through the application of natural products with inherent growth termination, stabilization, and capping characteristics are reviewed to provide an avenue to natural synthesis pathways to AgNWs. Future directions in both chemical and green synthesis approaches of AgNWs are addressed.

“…The polyol method is considered as an ideal method to synthesize Ag NWs due to its low cost, high yield and simple technology. 27,28 Nevertheless, complex and expensive raw material preparation process, weak adhesion on flexible substrates make AgNWs less stable in large strain ranges, and their application and development are limited to some extent. According to past reports, the composite of multiple nonconductive fillers can construct flexible strain sensors with more balanced performance.…”

Flexible strain sensors are attracting attention in areas such as medical monitoring sensing and rehabilitation therapy monitoring due to their powerful ability to sense, process, transmit and display complex information. However, it is an urgent challenge to realize the trade‐off between excellent performances such as high sensitivity, high linearity, wide strain sensing range and high durability. Herein, we prepare stretchable conductive composites with wrinkle composite micro‐crack structure by combining carboxystyrene butadiene rubber (XSBR) layer and carboxymethyl cellulose@Ag nanowire‐CNTs (CMC@AgNWs‐CNTs) conductive layer. Based on interfacial interactions, it can be adapted to different needs by adjusting the thickness of the strain sensing layer. When the thickness of the strain sensing layer is 4 μm, the strain sensor has a wide sensing range (strain capacity up to 300%) and high sensitivity (strain sensing factor of 484). At a thickness of 8 μm, the strain sensing performance exhibits a wide strain range, high linear fit and good cyclic stability. This work provides a new research idea to improve the comprehensive performance of flexible strain sensors and the contradiction between wide sensing range, high sensitivity and high linearity.
