Structure–property relationship of assembled nanowire materials

Abstract

Due to their unique structure, one dimensional (1D) nanomaterials have attracted considerable attention and shown potential applications in modern nano-devices. With advances in chemistry and materials science, integrating these 1D nanoscale-building blocks for macroscopic well-designed assemblies will provide new opportunities for sustainable and advanced applications. This article comprehensively reviews the structure–property relationship of assembled nanowire materials compared with the disordered NW statement. Specifically, we firstly highlight the anisotropy phenomenon of 1D assemblies, including the anisotropic conductive properties, optical properties, thermal conduction properties, and anisotropic strain sensing. Next, we systematically review the superior properties of ordered 1D assembly devices compared to random samples to elucidate the advantages of well-defined structures. The programmability of ordered assemblies with predictable architectures for large-scale devices is also briefly commented on. Finally, a summary and perspectives on challenges and future opportunities are presented.
