报告摘要：Bionic three-dimensional (3D) micro/nanostructures, due to their excellent physical and chemical properties, have been widely used in electronics, fluidics, sensing, and photonics. Herein, inspired by the work hardening phenomena in metal deforming, a sequential nano-micro-millimeter deforming process was employed to generate multiscale 3D patterns on the aluminum surface successfully. By combining with proper anodization, 3D anodized aluminum oxide templates were obtained, which can be employed as a cost-effective 3D lithography technique for the construction of customizable 3D architectures. This distinctive technique not only opens new opportunities for rapid prototyping of freeform 3D architectures on a large scale but also provides guidance for the quantitative analysis of the structure-property relationship and pursues excellent performance devices in many fields, such as flexible sensing and photon controlling.
