Alternative Materials for Conductive Inks

Technology Overview

High-aspect ratio metal nanowires (silver, copper and copper-nickel) are a suitable replacement for indium tin oxide (ITO) as material in creating transparent conducting electrodes, whose applications include tablets, smartphones, photovoltaics, light-emitting diodes (LED), liquid crystal displays (LCD), and flexible electronics. The material relies on fast, easy and scalable manufacturing through electroless deposition, and can be customised for a variety of products and unique user requirements. Its unique properties are ideal for foldable or rollable devices as well as strengthened glass and plastic substrates in future displays.

This technology has been demonstrated as a good alternative to expensive ITO transparent conducting films, which are scarce, brittle and vacuum-deposited.
