URBANA, IL and WEST LAFAYETTE, IN -- Researchers at Purdue University and the University of Illinois at Urbana-Champaign have successfully created networks of carbon nanotubes.

This technology will make it possible to create print circuits on plastic sheets for applications including flexible displays. Carbon nanotube transistors can be used to create high-performance, shock-resistant, lightweight and flexible integrated circuits. Nanonets are produced at low temperatures so the circuitry can be placed on flexible plastic sheets, reducing base material costs. 
 
Nanonets are circuits made of numerous carbon nanotubes that randomly overlap in a fishnet-like structure. Until recently, this technology has not demonstrated production robustness. The nanonet networks were often contaminated with random metallic nanotubes that caused shorts.

The problem was solved by cutting the net into strips to break the path of metallic nanotubes and eliminate the shorts.
 
The researchers created a flexible circuit containing more than 100 transistors, the largest nanonet ever produced and the first demonstration of a working nanonet circuit.
