Methods to Produce Ultra-Thin Copper Nanowires for Transparent Conductors

Patent Status

Brief Description

The disclosure provides innovative synthesis methods to produce uniform, ultrathin and high-quality metal nanostructures. In certain embodiments, the synthesis methods disclosed herein are solution based, therefore affording scalability and allowing for the production of metal nanostructures (e.g. Cu-nanowires ) that can have varying diameters, e.g., between 1 nm to 70 nm. The resulting metal nanostructures can be used to construct transparent electrodes that have lower costs, better transparency, and superior flexibility in comparison to conventional metal-oxide conductors, such as indium tin oxide (ITO) .

Suggested uses

- Optoelectronic devices e.g. touch panels, display electrodes (LCD & OLED), photovoltaic devices, electrochromic windows

Advantages

- Solution processable and patternable at low cost
- Highly flexible and transparent in large wavelength range
