Zhejiang University says Chinese researchers have for the first time identified an interlayer folded 'buckle' structure and mechanism in graphene membranes that enables simultaneous improvement in strength, toughness and elasticity. The study, which addresses the long-standing strength–toughness trade-off by moving beyond traditional planar stacking to construct interlocking folded layers, was published online in Nature at 23:00 Beijing time on the 14th.
