Researchers at Drexel University and Trinity College in Ireland have developed ink for an inkjet printer from MXene, a highly conductive two-dimensional material.

The MXene ink can be used to print flexible energy storage components, such as supercapacitors, in any size or shape; the technology is more conductive and more easily applied to a range of surfaces than other conductive inks.

The researchers tested the MXene ink in a series of printouts, including a simple circuit, a micro-supercapacitor, and some text, on substrates including paper, plastic, and glass.

The team found it could print lines of consistent thickness, and the ink's conductivity varied with its thickness, which are both important factors in manufacturing electronic components.

Said Drexel University's Babak Anasori, "Now that we have produced a MXene ink that can be applied via this technique, we're looking at a world of new opportunities to use it."
