Abstract

Graphical abstract: Highlights: Explosive-derived underwater shock wave enables ultralarge-area shock imprinting. The natural leaf mold reproduces microscale imprinting. The inertia of the phytolith causes the metal foil to start deforming. Abstract: Large-area nano-/microarray production in a single shot is a significant challenge in laser shock imprinting (LSI). Materials that can be used to fabricate molds easily will advance LSI techniques. Thus, here, an Al foil was compression-molded in a natural leaf mold using an explosive-derived underwater shock wave. The phytoliths' inertia triggered Al foil deformation, and microimprinting on an ultralarge area measuring 10 −2 m 2 was performed. The difference in the Al foil deformation rate caused by the phytoliths influenced the Al foil imprinting depth. Further, even a low-strength base to hold particles could be applied to the mold for LSI.
