Assembly of Nanowires into Macroscopic One-Dimensional Fibers in Liquid State
Natural structural materials, such as spider silk, wood, and bone, are universally acknowledged as the gold standard for the ideal combinations of strength and toughness. The exceptional integrated performance of these biological materials can be ascribed to their multiscale hierarchical architectures and components. Mimicking the hierarchical assembly feature of natural materials, artificial fibers, which are generated through the one-dimensional (1D) assembly of nanowires, have been widely reported with remarkable flexibility and functionality. Furthermore, the distinguishing feature of nanowires’ 1D assembly can bridge the unique properties of nanowires with their potential functional applications. This tutorial review summarizes the recent developments in the assembly of nanowires into macroscopic 1D fibers in the liquid state. We begin by introducing the general strategies and mechanisms for assembling nanowires in one direction and then, illustrate their potential applications in energy storage, sensors, biomedical engineering, etc. Finally, a brief summary and some personal perspectives on the future research directions of nanowires’ 1D assembly are also proposed.
