- Abstract
- Nanomaterial-delivery fabrication expects high-potential impacts on nanoscience, technology and industry, but still faces limited applicability mainly due to high-field requirement for liquid delivery, complicated intermediate processes, and narrow ink selectivity. Here, we demonstrates a simple, non-template, non-contact and electric field-free fabrication of diverse nanofibers. The process consists of continuous, meniscus-assisted delivery of liquid solutions through a nanoapertured nozzle in ambient conditions, followed by subsequent evaporation of liquid and aggregation of nanoparticle residues. For example, the carbon-nanotube nanofibers of 500 nm diameter exhibit a high shear modulus of similar to 1.5 GPa and current density up to 10(4) A/cm(2). The results provide a unique, universal and versatile tool with wide selectivity in both ink and substrate.
