Abstract

Amorphous alloys, i.e., metallic glasses, combine high strength, hardness, excellent wear and corrosion resistance, and unique thermoplasticity due to their short-range ordered but long-range disordered glassy structures. However, critical size constraints limit their applications in advanced fields such as electrocatalysis, sensing, and complex devices. Here we report a novel lattice metamaterial fabricated by conformally depositing NiNbSn amorphous alloy coatings onto three-dimensional (3D)-printed polymer scaffolds with a cubic micro-nano lattice template. The cubic lattice design enables efficient stress transfer and uniform strain energy distribution, minimizing stress concentration. Meanwhile, the NiNbSn coating, featuring amorphous and nanocrystalline components, further enhances the structure through size hardening. The resulting hybrid polymer/alloy lattice shows excellent mechanical properties and an exceptional energy absorption capacity. Furthermore, coating the hybrid lattice with a NiMoPB glassy film results in a 3D nano-micro electrode for glucose detection, achieving a sensitivity of 13 times higher than that of the cast-counterpart. Our strategy opens a new path to fabricating hybrid polymer/MGs micro-nano lattice structures with excellent mechanical and electrochemical performance, broadening the potential applications of metamaterials.

期刊介绍: Progress in Natural Science: Materials International provides scientists and engineers throughout the world with a central vehicle for the exchange and dissemination of basic theoretical studies and applied research of advanced materials. The emphasis is placed on original research, both analytical and experimental, which is of permanent interest to engineers and scientists, covering all aspects of new materials and technologies, such as, energy and environmental materials; advanced structural materials; advanced transportation materials, functional and electronic materials; nano-scale and amorphous materials; health and biological materials; materials modeling and simulation; materials characterization; and so on. The latest research achievements and innovative papers in basic theoretical studies and applied research of material science will be carefully selected and promptly reported. Thus, the aim of this Journal is to serve the global materials science and technology community with the latest research findings. As a service to readers, an international bibliography of recent publications in advanced materials is published bimonthly.
