Nanotube “Rebar” Makes Graphene Even Stronger

Posted by in categories: nanotechnology, particle physics, space

You may know graphene as a pseudo-legendary substance that could potentially revolutionize science and space travel and all sorts of things. If you don’t, you should get educated is pretty ridiculous. Simply made from carbon arranged into perfect one atom thing sheets makes the material one of the strongest ever observed. And, now, researchers at Rice University have found that so-called “rebar” graphene is dramatically tougher.

Graphene is much stronger than steel. In fact, an elephant could stand on a pencil and that pressure couldn’t break through a thin sheet of the material. But, because it is arranged in sheets, it can still be ripped if damaged from the right angle. But the researchers figured that reinforcing the structure, as we do with steel bars in concrete structures, l could help prevent damage.

The new research, published in the ACS Nano, a journal run by the American Chemical Society, Rice materials scientist Jun Lou and lead author Emily Hacopian examined the properties of rebar graphene under stress. Cracked and tears in the structure that otherwise would have spread across the sheet are stopped by the reinforcement while also staying stretchy and pliable.
