Flexible transparent electrodes (FTEs) have been widely witnessed in various printable electronic devices, especially those involving light. So far, solution processes have demonstrated increasing advantages in preparing FTEs not only in their mild operation conditions and high-throughput but also in the diversity in micropatterning conductive nanomaterials into networks. For the FTEs, both high transparency and high conductivity are desirable, which therefore create requirements for the conductive network by considering the trade-off relationship between the coverage and the micropatterns of the network. In addition, the conductive networks also affect the flexibility of FTEs due to the deformation during bending/stretching. Consequently, solution processes capable of micropatterning conductive nanomaterials including nanoparticles, nanowires/polymers, and graphene/MXene play a crucial role in determining the performance of FTEs. Here, we reviewed recent research progress on solution-processed FTEs, including the solution processes, the solution-processable conductive nanomaterials and the substrates for making FTEs, and applications of FTEs in flexible electronics. Finally, we proposed several perspective outlooks of the FTEs, which aim at not only the enhanced performance but also the performances in extreme conditions and in integration. We believe that the review would offer inspiration for developing functional FTEs.

用于可印刷电子产品的溶液处理柔性透明电极

柔性透明电极 (FTE) 已在各种可印刷电子设备中得到广泛应用,尤其是那些涉及光的电子设备。到目前为止,溶液工艺在制备 FTE 方面已显示出越来越大的优势,不仅在其温和的操作条件和高通量方面,而且在将导电纳米材料微图案化成网络的多样性方面。对于FTE,高透明度和高导电性都是可取的,因此通过考虑网络的覆盖率和微图案之间的权衡关系,对导电网络提出了要求。此外,由于弯曲/拉伸过程中的变形,导电网络也会影响 FTE 的柔韧性。因此,溶液工艺能够微图案化导电纳米材料,包括纳米颗粒,纳米线/聚合物和石墨烯/MXene 在决定 FTE 的性能方面起着至关重要的作用。在这里,我们回顾了溶液处理 FTE 的最新研究进展,包括溶液工艺、可溶液处理的导电纳米材料和用于制造 FTE 的基板,以及 FTE 在柔性电子中的应用。最后,我们提出了 FTE 的几个远景展望,其目标不仅是提高性能,还包括在极端条件下和集成中的性能。我们相信该审查将为开发功能性 FTE 提供灵感。可溶液加工的导电纳米材料和用于制造 FTE 的基板,以及 FTE 在柔性电子产品中的应用。最后,我们提出了 FTE 的几个远景展望,其目标不仅是提高性能,还包括在极端条件下和集成中的性能。我们相信该审查将为开发功能性 FTE 提供灵感。可溶液加工的导电纳米材料和用于制造 FTE 的基板,以及 FTE 在柔性电子产品中的应用。最后,我们提出了 FTE 的几个远景展望,其目标不仅是提高性能,还包括在极端条件下和集成中的性能。我们相信该审查将为开发功能性 FTE 提供灵感。
