New form of carbon that's hard as a rock, yet elastic, like rubber

A team including several Carnegie scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could serve a wide variety of applications from aerospace engineering to military armor.

Carbon is an element of seemingly infinite possibilities. This is because the configuration of its electrons allows for numerous self-bonding combinations that give rise to a range of materials with varying properties. For example, transparent, superhard diamonds, and opaque graphite, which is used for both pencils and industrial lubricant, are comprised solely of carbon.

In this international collaboration between Yanshan University and Carnegie - which included Carnegie's Zhisheng Zhao, Timothy Strobel, Yoshio Kono, Jinfu Shu, Ho-kwang "Dave" Mao, Yingwei Fei, and Guoyin Shen - scientists pressurized and heated a structurally disordered form of carbon called glassy carbon.

The glassy carbon starting material was brought to about 250,000 times normal atmospheric pressure and heated to approximately 1,800 degrees Fahrenheit to create the new strong and elastic carbon. Their findings are published by Science Advances.

Scientists had previously tried subjecting glassy carbon to high pressures at both room temperature (referred to as cold compression) and extremely high temperatures. But the so-called cold-synthesized material could not maintain its structure when brought back to ambient pressure, and under the extremely hot conditions, nanocrystalline diamonds were formed.

The newly created carbon is comprised of both graphite-like and diamond-like bonding motifs, which gives rise to the unique combination of properties. Under the high-pressure synthesis conditions, disordered layers within the glassy carbon buckle, merge, and connect in various ways. This process creates an overall structure that lacks a long-range spatial order, but has a short-range spatial organization on the nanometer scale.

"Light materials with high strength and robust elasticity like this are very desirable for applications where weight savings are of the utmost importance, even more than material cost," explained Zhisheng Zhao a former Carnegie fellow, who is now a Yanshan University professor.

"What's more, we believe that this synthesis method could be honed to create other extraordinary forms of carbon and entirely different classes of materials."

Oyster shells inspire new method to make superstrong, flexible polymers
New York NY (SPX) Jun 15, 2017
Researchers at Columbia Engineering have demonstrated for the first time a new technique that takes its inspiration from the nacre of oyster shells, a composite material that has extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a polymer initially well-mixed with nanoparticles, the team was able to control how the nanoparticle ... read more
