Materials Innovation: The Future of Stronger, Lighter, more Sustainable Materials

“Materials have always been about enthusiasm. Materials are a dream that we have realized. Everything is possible, it’s just that we have to make it happen,” says Mark Miodownik, the author behind the popular book Stuff Matters, in the fourth film of the Looking Ahead series.

The Age of New Materials

Throughout history, materials and advances in material technology have influenced humankind. Now we just might be on the verge of the next shift in this type of technology, enabling products and functions we never believed possible.
Demands from industry are requiring that materials be lighter, tougher, thinner, denser and more flexible or rigid, as well as to be heat- and wear-resistant. At the same time, researchers are pushing the boundaries of what we imagine is possible, seeking to improve and enhance existing materials and at the same time come up with completely new materials that, while years away from day-to-day use, take us down entirely new technological pathways.

The Sky is the Limit

Based on the research we’re seeing today, the field of applied material science is set to move in new, almost science-fiction-like directions. Looming resource scarcity is demanding innovations and out-of-the-box thinking.
On the materials front, composites with such desirable attributes as low weight, high strength and high durability look likely to take a larger market share, and more of these materials will likely be based on renewable resources, as the need for this becomes greater.

The most promising jewel in this arena is graphene. Only a single atom thick (1 million times thinner than a human hair), but 200 times stronger than steel by weight, extremely flexible, super light and almost transparent with great heat and electricity conductivity. It’s the stuff legends are made of.

In fact, researchers at Nankai University in Tianjin, China, recently found that a graphene sponge can turn light into energy, thus taking humankind one step closer to a fuel-free spacecraft, one that runs by the light of the sun.

Heading for the Graphene Revolution

Other potential areas of application for graphene range from water purification and energy storage to household goods, computers and other electronics. Meanwhile, although graphene-related patents are increasing by the thousands, widespread industrial adoption of graphene is limited by the expense of producing it – but that may be about to change. Researchers at the University of Glasgow have found a way to produce large sheets of graphene at a cost some 100 times cheaper than the previous production method.

Synthetic skin, capable of providing sensory feedback to people with limb prostheses, is one of the many possibilities that could grow out of this development. “Graphene could help provide an ultraflexible, conductive surface that could provide people with prosthetics capable of providing sensation in a way that is impossible for even the most advanced prosthetics today,” says Dr. Ravinder Dahiya, who led the research team at the University of Glasgow.

If it’s Broken, Let it Fix Itself

Nanocomposite research is opening up the possibility of materials that fix themselves, much the way the human body heals itself. Researchers at the Beckman Institute’s Autonomous Materials Systems Group at the University of Illinois in the United States are working on fiber-composite materials with self-healing properties that involve the integration of healing agents that are released to mix and polymerize when a defect is detected.

“Materials that heal themselves are coming,” says material scientist Mark Miodownik in the new Looking Ahead film, Tomorrow’s Materials. For now, what’s technically possible isn’t close to being reasonable economically, but the possibility of fixing anything on the fly, from airplane wings to bike frames to car parts crucial to the safety of vehicles and passengers, is on the horizon.

And it will have massive impact on product development, life cycle and sustainability. Researchers are even working on materials that will allow a roadway to repair itself instead of waiting for an overworked, understaffed maintenance crew.

Sustainability as a Key Driver

Material science and the development of new materials, as well as improvement of existing ones, look likely to play a crucial role in such areas as resource scarcity and sustainability. New materials – for example, light-absorbing building materials – could help counter global warming.

We seem to be on the verge of a new age, one that is characterized not only by digitalization and the Internet of Things but also, importantly, by new materials – materials that can make our future easier, safer and more sustainable. The sky really is the limit.


The Graphene Challenge –

Global innovation competition launched by Sandvik Coromant

On a mission to discover who can realize the full potential of graphene, Sandvik Coromant has initiated a global competition for individuals to submit ideas of how the application of graphene could be utilized in a way that would revolutionize the modern household.

Sandvik Coromant will consider all entries from high end industrial design to everyday useable items, beginning on April 7, 2016 and concluding on May 26, 2016. Participants are asked to submit ideas based around household objects that highlight how they could be improved with the use of graphene as a next-generation, innovative and sustainable materials. For more information, visit the Sandvik Coromant website.
