[Chinese scientists discovered the "interlayer folding buckle" structure of graphene film] October 15th, according to Zhejiang University, Chinese scientists discovered for the first time a new structure and new mechanism of "interlayer folding buckle" in graphene film, and the research can achieve a synergistic improvement in material strength, toughness and elasticity. The relevant results were published online in the international academic journal "Nature" at 23:00 on the 14th, Beijing time. For a long time, the improvement of the mechanical properties of graphene membranes has faced the bottleneck of "difficult to balance strength and toughness". Traditional methods have improved the performance by improving the regularity of the arrangement of graphene sheets or enhancing the bonding force between the sheets. The new research breaks through the traditional "planar stacking" design idea and constructs a graphene membrane with a folded and buckled structure that interlocks with each other.
