A new graphene material called diamene switches from flexible to harder-than-diamond upon impact

Researchers from 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. The material is fascinating as it is as flexible and lightweight as foil but becomes stiff and hard enough to stop a bullet on impact. Such a material may be beneficial for applications like wear-resistant protective coatings and ultra-light bullet-proof films.

The team worked to theorize and test how two layers of graphene could be made to turn 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.

"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" the team said.

The researchers used atomistic computer simulations to model potential outcomes when pressurizing two layers of graphene aligned in different configurations. They 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 transition does not occur for more than two layers or for a single graphene layer.

I really like this material because it’s very similar to my gel tech action suit idea. The only difference is my idea utilizes the spider silk scientists at the Wyoming University processed from genetically modified goats. I’m no expert but from what I’ve learned about the potential time crystals represent is that they are exactly what is needed to create (when combining the graphene material with elements from my super suit idea) to make a skin tight suit of armour that could change states of matter & protect the human body from danger in the most intense environments/activities like extreme sports, outer space/deep sea exploration. I imagine it would look very similar to the nano tech spider suit Tony Stark provides Peter Parker in the most recent Avengers film.

I had a theoretical idea utilizing diamene to form a bulletproof suit. Basically, you layer diamene on top of sorbothane, an incredibly shock absorbent material. With this combination, one could possibly design and build a bulletproof, not resistant but totally PROOF, suit.

That's exactly what I'm researching. Any updates you can share?

Thank you for your time.
