Researchers at City University of New York (CUNY) have created diamene, a flexible material using two layers of Graphene. Diamene can become harder than diamond during impact and offers protection even against a bullet, the research team claims. Graphene is lightweight and showcases strength due to its hexagonal lattice structure. The study team added that the thin film of diamene showcases better strength compared to a diamond during an impact. The sheets could be used to protect fragile objects or as a bulletproof vest.
Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY combined two layers of graphene (each layer just one atom thick) to create diamene. The research team also noticed that during impact, there was a reduction in electric current which suggests that the material could also be used for its electronic and spintronic characteristics. Experiments and theory both show that this graphite-diamond transition does not occur for more than two layers or for a single graphene layer.
Nanotechnology has the potential to change the way we develop electronics and the materials we use in different industries. Graphene has been in focus over the last few years due to its lightweight and strength. Thin sheets of graphene can be used in electronics. However, the biggest bottleneck in use of graphene on commercial scale due to limited technologies for its commercial production. Scientists are working on techniques to make commercial graphene production a viable option.
Researchers added that the thin sheets can be effectively used in developing wear-resistant protective coatings and ultra-light bullet-proof films.
The research paper detailing the project has been published in the journal Nature Nanotechnology.
