>>inherent defects give rise to a surprising mechanical property caused by an unusual mechanochemical reaction.What they discovered could potentially unlock the secret to successfully scaling up graphene oxide. “Our team discovered that graphene oxide exhibits remarkable plastic deformation before breaking,” said Espinosa. “Graphene is very strong, but it can break suddenly. We found that graphene oxide, however, will deform first before eventually breaking.”

Huang compares the difference in the materials’ properties to common objects. “Ceramic is strong,” he says, “but if you break it, it will shatter...
