From: Coating two-dimensional MoS2 with polymer creates a corrosive non-uniform interface

The instability mechanisms at the interfaces. a The buckling and cavity formation by corrugations at interfaces. b The instability caused by stress gradient originated from inhomogeneous evaporation of solvents. c The scheme for bowtie shape 2D flakes with buckling inside domains rather than at domain boundaries (red arrows). 2D atomic layers at the interface are not shown, they might be attached either to the soft coating or the rigid substrate after buckling
