A potentially revolutionary change in body armor....

Cops have a love-hate relationship with body armor. No question, it's saved countless lives over the years. It is also uncomfortable, especally for those of us in hot areas. There has been some possible changes in body armor, from some based on corn starch, and liquid. But if this works out, it's a real game changer.

Graphene Research Could Lead to Foil-Thin Body Armor

Some scientists believe the combination of two graphene layers could create a lightweight material that can stop bullets.

Researchers from the City University of New York’s Advanced Science Research Center discovered that by combining no more than two layers of graphene, they would be able to create an ultra-thin material that, when it is struck by a fast-moving projectile like a bullet, it suddenly hardens and protects the wearer, Morning Ticker reports.

Graphene is a sheet of a single layer of carbon atoms that is arranged in hexagonal fashion. Scientists have discovered that graphene has some extremely unusual properties, as it is the strongest material that has ever been tested and it very efficiently conducts heat and electricity. It was first observed by an electron microscope back in 1962, but it wasn’t until 2004 that scientists were able to isolate and characterize graphene.

Here is the full statement from the research center:

Imagine a material as flexible and lightweight as foil that becomes stiff and hard enough to stop a bullet on impact. In a newly published paper in Nature Nanotechnology, researchers across The City University of New York (CUNY) describe a process for creating diamene: flexible, layered sheets of graphene that temporarily become harder than diamond and impenetrable upon impact.

Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY, worked to theorize and test how two layers of graphene — each one-atom thick — could be made to transform into a diamond-like material upon impact at room temperature. The team also found the moment of conversion resulted in a sudden reduction of electric current, suggesting diamene could have interesting electronic and spintronic properties. The new findings will likely have applications in developing wear-resistant protective coatings and ultra-light bullet-proof films.

“This is the thinnest film with the stiffness and hardness of diamond ever created,” said Elisa Riedo, professor of physics at the ASRC and the project’s lead researcher. “Previously, when we tested graphite or a single atomic layer of graphene, we would apply pressure and feel a very soft film. But when the graphite film was exactly two-layers thick, all of a sudden we realized that the material under pressure was becoming extremely hard and as stiff, or stiffer, than bulk diamond.”

Angelo Bongiorno, associate professor of chemistry at CUNY College of Staten Island and part of the research team, developed the theory for creating diamene. He and his colleagues used atomistic computer simulations to model potential outcomes when pressurizing two honeycomb layers of graphene aligned in different configurations. Riedo and other team members then used an atomic force microscope to apply localized pressure to two-layer graphene on silicon carbide substrates and found perfect agreement with the calculations. Experiments and theory both show that this graphite-diamond transition does not occur for more than two layers or for a single graphene layer.

“Graphite and diamonds are both made entirely of carbon, but the atoms are arranged differently in each material, giving them distinct properties such as hardness, flexibility and electrical conduction,” Bongiorno said. “Our new technique allows us to manipulate graphite so that it can take on the beneficial properties of a diamond under specific conditions.”

The research team’s successful work opens up possibilities for investigating graphite-to-diamond phase transition in two-dimensional materials, according to the paper. Future research could explore methods for stabilizing the transition and allow for further applications for the resulting materials...

...Scientists believe it could be used to create solar cells, light-emitting diodes (LED), touch panels, or even phones. Researchers think that it would be possible to create graphene supercapacitors that would be able to replace electrolytic batteries as an energy storage device. And the auto industry is even experimenting with making cars out of this material...

Cool on the other items, but if this is usable for body armor, it's nothing short of incredible. K9s, horses, and two legged cops will have no excuse for not wearing protection from firearms.
