Pristine monocrystalline graphene is claimed to be the strongest material known with remarkable mechanical and electrical properties. However, graphene made with scalable fabrication techniques is polycrystalline and contains inherent nanoscale line and point defects—grain boundaries and grain-boundary triple junctions—that lead to significant statistical fluctuations in toughness and strength. These fluctuations become particularly pronounced for nanocrystalline graphene where the density of… Expand

Enhancing the Strength of Graphene by a Denser Grain Boundary.
TLDR
A systematic study on the effect of elastic modulus and breaking strength of CVD-derived graphene films with a controlled density and distribution ofGBs finds that graphene films become much stronger by hugely increasing the density of GBs without triple junctions formed inside, in analogy to the two-dimensional plum pudding structures.

Toughening Graphene by Integrating Carbon Nanotubes.
TLDR
This work identifies a promising extrinsic toughening strategy for 2D materials and provides mechanistic insights into the fracture process of graphene hybrid material. Expand

Inverse Pseudo Hall-Petch Relation in Polycrystalline Graphene

Using atomistic calculations, graphene sheets with large-angle tilt boundaries that have a high density of defects are as strong as the pristine material and, unexpectedly, are much stronger than those with low-angle boundaries having fewer defects. Expand
