Free-standing All-nanoparticle Thin Fibers: A Novel Nanostructure Bridging Zero- And One-dimensional Nanoscale Features

摘要

Nanoscience and nanotechnology have had great success in revealing nanostructures with unique dimensionalities. To highlight a few, nacre is composed of nanolayers of inorganic crystallites and biopolymers and is therefore 2D in nature and exhibits extraordinary toughness. Derivatives of such a structure can be utilized to suit a variety of engineering applications due to their fine structure. Nanotubes, nanobelts, or nanofibers all possess a ID structure, where the long dimension promotes applications for advanced functional materials and the short dimension delivers superior electronic, mechanical, or electromechanical properties. Long-lasting impacts of these ID features are being generated in multiple fields. For example, nanotubes could be used as scanning probes to provide unprecedented resolution to scanning probe micro-scopy, continuous nanofibers can be efficient intermediate layers in nanocomposites, and functional nanobelts demonstrating an electromechanical coupling effect can be potential candidates to power future nanosystems.
