Abstract
Nanolattices exhibit attractive mechanical, energy conversion, and optical properties, but it is challenging to fabricate large nanolattices while maintaining the dense regular nanometre features that enable their properties. In this work, we report a crack-free self-assembly approach for fabricating centimetre-scale nickel nanolattices with a feature size of 100 nm and a grain size of 30 nm. The crack-free areas are 20,000 times larger than prior self-assembled nanolattices and contain 1,000 times the number of unit cells as 3D-printed nanolattices. These nickel nanolattices have a 260 MPa tensile strength, which approaches the theoretical strength limit for porous nickel and is 10 times the strength of prior nanolattices. The self-assembly method and porous metal mechanics reported in this work advances the fabrication and applications of high-strength multifunctional porous materials.
