A scalable fabrication strategy is reported for the solution‐based electrochemical fabrication of microscale metal meshes from reusable, non‐sacrificial templates. This approach enables the reproducible fabrication of meshes, potentially made of any electrochemically depositable metal and transferable to a variety of polymeric substrates. Unlike other existing approaches, this benchtop method repetitively mass‐produces metal meshes whose geometric features are predefined by a template, without requiring lithography or any vacuum processes in each production cycle. Using this technique, a number of prototype‐flexible and stretchable transparent electrodes with an embedded metal mesh with micro‐sized linewidths are demonstrated with transmittance as high as 90% and sheet resistance as low as 0.036 Ω□⁻¹, corresponding to a high figure of merit of 3.4 × 10⁴ at 4 μm mesh linewidth, and the electrodeposition template showed no degradation after at least 20 production cycles. In addition to outstanding optical and electrical performances, the resulting electrodes show excellent mechanical robustness and stability against chemicals and harsh environment. The electrodes are further tested in flexible bifacial dye‐sensitized solar cells and stretchable transparent thin‐film heaters, confirming their suitability and reliability for practical applications.

用于柔性和可拉伸电子设备的模板电沉积和压印转移微型金属网透明电极

据报道，从可重复使用的，非牺牲性的模板中，基于解决方案的微型金属网的电化学制造可扩展的制造策略。该方法使得网的可再现制造成为可能，该网可能由任何电化学可沉积的金属制成并且可以转移到各种聚合物基底上。与其他现有方法不同，这种台式方法可以重复批量生产其几何特征由模板预定义的金属网格，而无需在每个生产周期中进行光刻或任何真空工艺。使用该技术，展示了许多具有可嵌入金属网且具有微小线宽的原型柔性和可拉伸透明电极，其透射率高达90％，薄层电阻低至0.036Ω□ ^-1，对应于在4μm网格线宽下为3.4×10 ⁴的高品质因数，并且电沉积模板在至少20个生产循环后仍未发生降解。除了出色的光学和电气性能外，所得电极还具有出色的机械强度和抗化学药品及恶劣环境的稳定性。电极在柔性双面染料敏化太阳能电池和可拉伸透明薄膜加热器中进行了进一步测试，证实了它们在实际应用中的适用性和可靠性。
