Länk - Papper starkt som stål: Tyvärr känsligt för vatten

The process works like this: the team disperses graphene oxide particles in specially treated water and then draws the mixture through a filter membrane. The water somehow causes the particles to bind into a paperlike layer on the filter's surface, the researcher reports in tomorrow's Nature. "We actually don't know all of the details of how the layering takes place," says physical chemist and co-author Rod Ruoff. Laboratory tests showed that the grapheme paper was as strong as that made from carbon nanotubes, yet unlike nanotubes, the material can be fabricated to any size. That makes graphene paper a prime candidate for a new generation of superstrong composite materials, Ruoff says.
