3D graphene: MIT scientists develop super-light, super-strong structure

Posted Date 01/20/17

Scientists at MIT have figured out how to build up graphene into useful, 3-D shapes with the potential to be lighter and stronger than steel.

The journal Science Advances published the results of the MIT study, describing how the researchers created a porous, three-dimensional graphene material. During the synthesis of the graphene, the team added heat and pressure in order to compress small flakes of graphene together, creating complex spongelike structures similar to corals and diatoms, a kind of unicellular algae. These structures, while not very dense, have a large surface area and are extremely strong; one graphene sample had only 5 percent of the density of steel, but was 10 times stronger.
