Transparent conducting film (TCF) is a critical component in displays including touch panel displays. Currently, there has been considerable research in using a printable technology for indium tin oxide (ITO) or aluminum-doped zinc oxide (AZO) films, but low sheet resistance has been unattainable.

Researchers at Purdue University have developed a laser heating of composite TCF composed of silver nanowires (AgNws). This technology will form a high quality TCF on a flexible substrate without melting the substrate at high temperatures. It will target laser assisted printing of a new nanocomposite material for TCF, resulting in a higher quality than current technologies in both properties and cost.

Advantages:
-Abundant materials
-Superior performance
-Low cost
-Robust reliability and lifetime

Potential Applications:
-Touch screens
-Displays
-Laser Assisted Printing
