摘　　要：Metallic nanowire arrays （NWAs） possess wide application prospects due to their unique property, and the tailoring of NWAs＇ structure and morphology is of importance since it would significantly influence the per- formance of NWAs. In the present work, the morphology and structure evolution of the NWAs prepared by the newly developed die nanoimprinting technique has been investigated in detail. It was found that increasing pro- cessing temperature, time and pressure could increase the length of the nanowires and change the NWAs＇ morphol- ogy from monodispersed form to aggregated form. Increasing processing time and temperature within the supercooled liquid region would promote crystallization, while increasing processing pressure could suppress the crystallization. This work provided important insights into the structure and morphology evolution, and therefore, the tailoring of metallic NWAs prepared by die nanoimprinting through adjusting the process parameters.金属性的 nanowire 数组(NWA ) 由于他们的唯一的性质，并且定制 NWA 拥有宽应用程序前景自从它将显著地影响 NWA 的性能，结构和形态学具有重要性。在现在的工作， NWA 的形态学和结构进化准备了由最新发展了死 nanoimprinting 技术详细被调查了。增加处理温度，时间和压力能增加 nanowires 的长度并且从 monodispersed 形式把 NWA 形态学改变到聚集的形式，这被发现。增加在 supercooled 液体区域以内处理时间和温度将支持结晶化，当增加处理压力能压制结晶化时。这个工作提供了重要卓见进结构和形态学进化，因此，定制金属性的 NWA 准备了由死通过调整过程参数的 nanoimprinting。
