We have developed the low-temperature conformal ZnO nanowire fabrication on flexible plastic substrates by utilizing the solution-processible metal seed-assisted hydrothermal ZnO crystallization. Structural evolution of ZnO nanowires controlled by major parameters involving growth temperature, growth time, and seed coating condition, has been systematically investigated towards uniform and large-area growth of conformal ZnO nanowires. Direct ZnO nanowire growth on flexible plastics without undergoing the high-temperature seed sintering has been realized by developing the low-temperature Ag-seeded hydrothermal ZnO nanowire growth. The nanoporous Ag layer favorable for ZnO crystal nucleation and continued nanowire growth can be reduced from the Ag ion solution coating at the temperature as low as 130 °C. This tactfully enables the selective hydrothermal growth of ZnO nanowires on the Ag patterns on flexible plastics. Such an all-solution-processible low-temperature fabrication protocol may provide an essential and practical solution to develop many diverse applications including wearable and transparent electronics, sensors, and photocatalytic devices. As one example, we demonstrate that a transparent UV sensor can be devised based on the ZNW growth on the Ag micromesh electrode.

通过可溶液加工的金属种子水热生长在柔性塑料基板上低温大面积制造ZnO纳米线。

通过利用可溶液加工的金属种子辅助水热ZnO结晶技术，我们在柔性塑料基板上开发了低温共形ZnO纳米线制造技术。已对涉及生长温度，生长时间和种子包被条件的主要参数控制的ZnO纳米线的结构演变进行了系统研究，以求获得共形ZnO纳米线的均匀和大面积生长。通过开发低温Ag播种的水热ZnO纳米线生长技术，已经实现了在柔性塑料上直接进行ZnO纳米线生长而不进行高温种子烧结。可以在低至130°C的温度下从Ag离子溶液涂层中还原出有利于ZnO晶体成核和纳米线连续生长的纳米多孔Ag层。这巧妙地实现了在柔性塑料上的Ag图案上ZnO纳米线的选择性水热生长。这种可全溶液处理的低温制造协议可以为开发许多不同的应用程序（包括可穿戴和透明电子设备，传感器和光催化设备）提供必要的实用解决方案。作为一个示例，我们证明了可以基于Ag微网电极上ZNW的增长来设计透明的紫外线传感器。
