Ultrathin Copper Nanowire Synthesis with Tunable Morphology Using Organic Amines for Transparent Conductors
High-quality
monodispersed copper nanowires with an ultrathin diameter
of 13.5 nm, lengths up to 30 μm (aspect ratio >10<sup>4</sup>) were successfully synthesized by a facile and controllable hydrothermal
reduction procedure. The synthesis utilized glucose in the presence
of hexadecylamine (HDA) and octadecylamine (ODA) as the capping agents.
The copper decahedra nanoparticles with a low-surface-energy {111}
plane formed pentatwinned one-dimensional nanowires, which was exactly
verified by selected-area electron diffraction. Furthermore, the diameter
and relative film conductivity of copper nanowires are sensitive to
the HDA/ODA molar ratio. The conductor film made of the high-quality
and ultrathin copper nanowires shows high transmittance and low resistance
(83.83%, 61 Ω/□), exhibiting great potential in the applications
of nanofabrication, transparent and flexible conductors, organic light-emitting
diodes, and more
