Dressels researchers help print flexible energy storage components with MXene Ink
Researchers from Drexel University and Trinity College in Ireland, have created ink for an inkjet printer from a highly conductive type of two-dimensional material called MXene. Recent findings, published in Nature Communications, suggest that the ink can be used to print flexible energy storage components, such as supercapacitors, in any size or shape.
Yury Gogotsi, PhD, Distinguished University and Bach professor in Drexel's College of Engineering, Department of Materials Science and Engineering, who studies the applications of new materials in technology, suggests that the ink created in Drexel's Nanomaterials Institute is a significant advancement on both of these fronts.
“So far only limited success has been achieved with conductive inks in both fine-resolution printing and high charge storage devices,” Gogotsi said. “But our findings show that all-MXene printed micro-supercapacitors, made with an advanced inkjet printer, are an order of magnitude greater than existing energy storage devices made from other conductive inks.”
While researchers are steadily figuring out ways to make inks from new, more conductive materials, like nanoparticle silver, graphene and gallium, the challenge remains incorporating them seamlessly into manufacturing processes. Most of these inks can't be used in a one-step process, according to Babak Anasori, PhD, a research assistant professor in Drexel's department of Materials Science and Engineering and co-author of the MXene ink research.
“For most other nano inks, an additive is required to hold the particles together and allow for high-quality printing. Because of this, after printing, an additional step is required — usually a thermal or chemical treatment — to remove that additive,” Anasori said. “For MXene printing, we only use MXene in water or MXene in an organic solution to make the ink. This means it can dry without any additional steps.”
MXenes - two-dimensional layered material
MXenes are a type of carbon-based, two-dimensional layered materials, created at Drexel in 2011, that have the unique ability to mix with liquids, like water and other organic solvents, while retaining their conductive properties. Because of this, Drexel researchers have produced and tested it in a variety of forms, from conductive clay to a coating for electromagnetic interference shielding to a near-invisible wireless antenna.
Adjusting the concentration to create ink for use in a commercial printer was a matter of time and iteration. The solvent and MXene concentration in the ink can be adjusted to suit different kinds of printers.
“If we really want to take advantage of any technology at a large scale and have it ready for public use, it has to become very simple and done in one step,” Anasori said. “An inkjet printer can be found in just about every house, so we knew if we could make the proper ink, it would be feasible that anyone could make future electronics and devices.”
As part of the study, the Drexel team, working with researchers at Trinity College, who are experts in printing, put the MXene ink to the test in a series of printouts, including a simple circuit, a micro-supercapacitor and some text, on substrates ranging from paper to plastic to glass. In doing so, they found that they could print lines of consistent thickness and that the ink's ability to pass an electric current varied with its thickness — both important factors in manufacturing electronics components. And the printouts maintained their superior electric conductivity, which is the highest among all carbon-based conductive inks, including carbon nanotubes and graphene.
This all amounts to a very versatile product for making the tiny components that perform important, but often overlooked functions in our electronics devices — jobs like keeping the power on when the battery dies, preventing damaging electrical surges, or speeding the charging process. Providing a higher-performing material and a new way to build things with it could lead not only to improvements to our current devices, but also the creation of entirely new technologies.
“Compared to conventional manufacturing protocols, direct ink printing techniques, such as inkjet printing and extrusion printing, allow digital and additive patterning, customization, reduction in material waste, scalability and rapid production,” Anasori said. “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.”

HP launches dye-sub printers to foray into into textile printing
HP will make its first-ever moves into the textiles printing market by launching two machines in its new Stitch S series of dye-sublimation printers, with a third on the way for Fespa.
The 1.6m-wide Stitch S300 and S500 printers will be available from June after being debuted at the ISA 2019 in April.
HP said the Stitch S300 had been designed for ease-of-use and is intended for entry-level or minimal-use markets. It comes with HP's Ergosoft RIP, HP transfer paper and the manufacturer's full profile library. It is capable of both transfer and direct-to-fabric printing.
Its sibling, the S500, was described by HP global business director for textiles Ester Sala as a “workhorse” for high-production operations, designed to keep up with demanding workloads in markets such as sportswear, interior decor and soft signage.
Both machines will be followed in July by the 3.2m Stitch S1000, which was presented under exclusive invitation at ISA and will receive its public unveiling at Fespa 2019 in Munich. Details on the S1000 are scant as yet and will be revealed at the show.
“The digital printing market is worth $3.6bn [£2.77bn] and polyester makes up 60% of the square-meterage that is printed,” said Sala. “It is expected to continue growing to a point where its demand is doubled by 2030 and the more it grows, the more dye-sublimation will grow, too.
“It is because of this that we have decided to move into the four key markets of soft signage, interior decor, sportswear and apparel. Across these markets, it is the same pain points that they have in common: colour management, waste and inefficiencies, and delivery times.
“We have been working closely with customers during the development stages of the Stitch family to make sure we come up with the best solution possible.”
A pioneering feature of the Stitch family will be its user-replaceable printheads which Sala said “will bring a lot of peace of mind to users in a very manual industry” by saving on downtimes.
Features including automated maintenance, the ability to take papers as light as 25gsm and a variety of hardware built in for image, colour and banding control have been touted by HP as reasons the Stitch is a unique proposition in the textiles market.
The S500 runs a symmetrical eight-head dual-CMYK configuration and is designed to maintain colour and quality consistency at speeds up to 110sqm/hr, billed by Sala as “twice as fast as the fastest machine currently on the market”.
Alongside the printers, HP has also launched its own branded dye-sublimation papers and a specialised dye-sub thermal inkjet ink billed as the first of its kind by HP.
Going forward, the Stitch branding will be an umbrella term for all HP machinery in the textiles sector.
The family of machines, including the full show debut of the S1000, will appear on HP's stand at Fespa 2019, set to take place at Messe Munich on 14-17 May.
Macclesfield-based wide-format kit vendor RA Smart has been named as HP's chosen reseller for the Stitch family in the UK and Ireland.
