Chinese scientists have developed a new foam-like ‘super material’ that is – to use a simile – as light as a balloon yet as strong as metal.

The foam-like material was created when tiny tubes of graphene were formed into a cellular structure which boasted of the same stability as a diamond.

Graphene has attracted great interest among researchers in recent years. And this was what led the researchers at the Chinese Academy of Sciences’ Shanghai Institute of Ceramics to develop the new material.

About 207 times stronger than steel by weight and able to conduct heat and electricity with very high efficiency, the new foam-like material is been designed to support something 40,000 times its own weight without bending, reports science journal, Advanced Materials.

The researchers contend that one piece of the graphene foam can easily withstand the impact of a blow that has a force of more than 14,500 pounds per square inch – almost as much pressure experienced at the world’s deepest depth in the Pacific ocean known as Challenger Deep of the Mariana Trench.

It is for this reason that the Shanghai research team said their newly created material could withstand more external shocks than other previously reported graphene materials.

It could also be squashed to just 5 per cent of its original size and still return to its original shape, and remained intact after the process was repeated 1,000 times.

Primarily destined for military applications, the properties of the novel material implies that it could be used as a cushion under the surface of bulletproof vests or on the outside of tanks to absorb the shocks from incoming projectiles, the Shanghai study said.
