Scientists create new graphene-based printer ink

Scientists have developed an ink using tiny graphene flakes that when used in inkjet-printers can produce finely detailed and highly conductive electrodes.

A new US study shows these printed graphene patterns are about 250 times more conductive than previously produced. It also has the ability to withstand folding with only a slight decrease in conductivity.

Inkjet printing is useful for printing electronic components because it's low-cost, can print large areas and on flexible layers.

Graphene inks have the potential to impact printed, flexible and foldable electronics. Some examples include smartphones, tablets, flat panel displays, and photovoltaics.
