摘要

In two-dimensional polycrystalline graphene,two angular degrees of freedom (DOF) areneeded to define a general grain boundary (GB):the misorientation of two grains and the rotationof the boundary line.Via both molecular dynamics simulations and theoretical analysis,we see that the density of GB defects strongly depends on grain misorientation but is insensitiveto GB rotation.And reveal the dependence of mechanical properties on grain misorientation andGB rotation in polycrystalline graphene.We find that the dependence of GB normal strengthon grain misorientation and GB rotation in graphene stems from the superposition of the stressfield induced by a pentagon-heptagon pair itself to that from the interaction between the otherdefects and the one under consideration.
