Researchers from Singapore National University, along with Rice University scientists, developed a single carbon, a new two -way material, turned out to be eight times stronger than Graphene. . The work is published in Matter magazine.
Grafen is one of the strongest materials on Earth, but he has a serious drawback: if a crack appears in it, it spreads very quickly, making the material fragile. This limits its use in real devices, especially in areas that require high mechanical stability.
New materials, like grafen, only consists of a carbon atom. However, he has a heterogeneous structure, combining both areas that are ordered (crystals) and erratic (amorphous). This is what gives him unique power and ability to resist the formation of cracks.
Such a design prevents the rapid spread of cracks, allowing the material to absorb more energy before destroying, he explains the Boongki Shin, co -author of the study.
To study Mac's mechanical properties, scientists used spacing tests inside the scan microscope, which allows observing the formation of cracks in real time. They also conducted a computer model at an atomic level. This can understand how amorphous areas and crystals interact and how they prevent the spread of cracks.
Previously, such studies were impossible, because the creation and visualization of extremely amorphous materials at the atomic level was a difficult task. But thanks to the new synthesis methods and high microscopes, we have done this, Professor Yem Khan said.
According to scientists, new discovery can lead to the creation of strong and stable components for the technology of the future.
