MATERIAL WITNESSES — RESEARCHERS AROUND THE WORLD ARE DELVING INTO DREXEL’S 2D MXENE

Rus На русском Eng In English

More than twenty 2D carbides, nitrides and carbonitrides of transition metals (MXenes) have been synthesized and studied, and dozens more predicted to exist. Highly electrically conductive MXenes show promise in electrical energy storage, electromagnetic interference shielding, electrocatalysis, plasmonics and other applications.

It’s been just over five years since researchers in Drexel’s Department of Materials Science and Engineering reported on a new, two-dimensional material composed of titanium and carbon atoms. on the cover of the latest edition of Nature Reviews MaterialsTheir creation, dubbed MXene, which is, cleverly, both chemical shorthand for the material and a homonym of Maxine, is now the focus of research at dozens of partner institutions from countries spanning every continent but Antarctica. And a feature story, on the cover of the latest edition of Nature Reviews Materials, suggests that even more should take up the pursuit. 

MXene entered the conversation, in the midst of a flurry of research around the idea that atom-thick materials could be the key to building smaller, faster electronics; improving energy storage devices; adding impressive durability to products from tennis rackets to military equipment; and even repairing damaged neurons. Most of this excitement stemmed from the discovery of the amazing properties of two-dimensional graphite — called graphene — and the Nobel Prize awarded to the researchers at the University of Manchester who first reported them.

Researchers around the world are looking at MXene for a variety of applications. In the U.S. and China alone, more than 60 research centers have taken up the pursuit, including Oak Ridge National Lab, Columbia University, Northwestern University, Stony Brook University, the University of Pennsylvania, Penn State University, Rice University, Yale University, Stanford University, the University of Nebraska — Lincoln, Texas A&M University, the University of California Davis, Missouri Tech, Peking University, Zhejiang University, Yanshan University, Lanzhou University, Beihang University, Chinese Academy of Sciences, the City University of Hong Kong and Shaanxi University of Science & Technology

The initial excitement about graphene as the next “miracle material” with “very attractive properties” — which would put it in a category with things like aluminum, steel and plastic — has been tempered in recent years, because it has not found many real-world applications thus far, despite huge investments into research that resulted in more than 60,000 papers being published about it since 2004. But MXene is one of its contemporaries that is still being explored for many of the same uses, and already showing better performance in some of them.

“MXenes are a worthy research subject because there are so many MXenes and they have already shown unique properties, outperforming other materials in several applications,” said Babak Anasori, PhD, a research assistant professor in the A.J. Drexel Nanomaterials Institute and the lead author of the Nature Reviews Materials article.

MXene shows tremendous potential for use in energy storage devices, according to Yury Gogotsi, PhD, the principal investigator on the project that led to MXene’s discovery, who is the Distinguished University and Trustee Chair Professor at Drexel and director of the Nanomaterials Institute. Gogotsi’s team has published extensively on the material’s ability to hold and discharge electricity at exceptional rates without deteriorating. This is one area where MXene has a clear leg up on its forerunner, because its conductive properties can be controlled and have even proven to be highly tunable. And while graphene displays unparalleled electrical conductivity, it is difficult to control the torrential flow of current through it — which is a necessity for any material with aspirations of being used in electronic devices. 

Gogotsi’s research also suggests that MXene has surpassed the impressive conductivity of graphene when both are scaled up to the paper-thin form that would be used in battery electrodes. And at the other end of the spectrum, MXene in its thinnest form, which is transparent, also exhibits superior conductivity to a graphene coating. Researchers are examining the possibility of using MXene films for touch screen technology and transparent energy storage devices.

Researchers from the A.J. Drexel Nanomaterials Institute have been studying MXene for nearly half a decade. (L-R): Olekisy Gogotsi (Director of Materials Research Center, Ukraine), Gabriel Scull, Babak Anasori, Mohamed Alhabeb, Yury Gogotsi.

Researchers in Gogotsi’s lab have also examined MXene for use as a chemical “strainer,” of sorts. Their experiments have focused on its ability to trap other molecules and ions in its atomic structure, while allowing others to pass, unimpeded. This property could be useful in corralling toxins in the body, as well as in our drinking water.

Layering other elements or compounds between sheets of MXene also produces promising results when it comes to enhancing the material’s durability. Inserting a polymer generates a version of the material that could be used for flexible electrodes in energy storage and wearable technology.

Most recently, the group has published on MXene’s ability to block another pesky intruder: electromagnetic radiation. The discovery that MXene can ward off electromagnetic interference from our ubiquitous, mobile devices seems to hold a great deal of promise because a thin layer of MXene (10 times thinner than a sheet of paper) is extremely effective as a spray coating that could be applied to individual components inside the devices.

One of the most promising new developments with MXene has revealed that a thin coating of it could be used for electromagnetic shielding in mobile devices.One of the most intriguing aspects in the pursuit of understanding how this material can be used is that it can be made with quite a variety of atoms. To date, MXene researchers have produced about two dozen distinct MXenes — moving on from the original titanium and carbon “recipe” to produce the material with pairings that have linked most of the elements in titanium’s group (the early transition metals) with both carbon and nitrogen — resulting in MXenes with their own unique properties. And the group has identified that more than 100 other combinations can be produced as stable materials.

Herein lies the research challenge offered up in the Nature Materials Reviews piece. As new MXenes are being produced and explored, researchers suggest that they will get closer to understanding the ion dynamics between layers of MXene, which will be key to using them for developing new kinds of batteries. So too will be the effort to create MXenes with uniform terminations so they can be tailored for particular uses in electronics — this is roughly equivalent to making sure every shape and size of Lego block has the same round connectors so they’re compatible with the rest of the set.

And, as with graphene, the cost of producing the material is a key determinant in whether or not it’s viable to move forward with research. Michel Barsoum, PhD, distinguished professor in Drexel’s College of Engineering, who discovered MXene along with Gogotsi, and whose research focuses on synthesizing its chemical precursor, MAX Phase, recently published about a low-cost method for churning it out, which could drop the cost of MXene well below graphene.

Each of these challenges is an important hurdle that MXene must overcome on the way to being commercially viable, according to Gogotsi. But the team has made promising strides in scaling up its production process while also improving quality control. While most nanomaterials are only available in “nano” quantities, Gogotsi’s lab can make as much as 100 grams of MXene at a time, using a reactor developed with the Materials Research Center in Ukraine. This means that one of the biggest obstacles is out of the way and, with the help of broadening research efforts, MXene could soon be a name in technology as well.

While most nanomaterials are only available in “nano” quantities, Gogotsi’s lab can make as much as 100 grams of MXene at a time, using a reactor developed with the Materials Research Center in Ukraine.

“The fact that they can be produced in 100-gram quantities in the lab is a breakthrough that clearly shows that their practical applications are real,” Gogotsi said.

Since 2011, Gogotsi’s team has received just over $1 million to support its MXene research from funders that include the U.S Department of Energy, Oak Ridge National Laboratory and King Abdullah University of Science and Technology in Saudi Arabia. To ensure its commercial viability, when the time comes, Drexel has done extensive work to protect the intellectual property related to MXene, which covers compositions of matter, applications and methods of manufacture. According to Elizabeth Poppert, PhD, the licensing manager in Drexel’s Office of Technology Commercialization who handles MXene’s IP, its portfolio currently includes three issued patents that cover broad composition of matter claims, with 10 additional pending international and U.S. patent applications.
