Printing Graphene With Ink-jets

Printing Graphene With Ink-jets

Printing graphene with ink-jet technology has been difficult because it tends to breakdown conductivity. Researchers at Northwestern University have developed a new method of producing graphene flakes that can be mixed into an ink form to be printed while still retaining conductivity and flexibility. This is a move toward being able to print inexensive flexible transistors, solar cells and other electronic components.

Opening Doors to Foldable Electronics with Inkjet-Printed Graphene – [northwestern.edu]

Imagine a bendable tablet computer or an electronic newspaper that could fold to fit in a pocket.

The technology for these devices may not be so far off. Northwestern University researchers have recently developed a graphene-based ink that is highly conductive and tolerant to bending, and they have used it to inkjet-print graphene patterns that could be used for extremely detailed, conductive electrodes.

The resulting patterns are 250 times more conductive than previous attempts to print graphene-based electronic patterns and could be a step toward low-cost, foldable electronics.
