Considering that these substitution and destabilization processes include the breaking process of charge-dipole bonds between the closest layer and the solid surface, the disappearance rate of the layered structure could also be dominated by the activation energy to break the charge-dipole bonds, which is larger than that for the bulk viscous flow. Nevertheless, as mentioned above, the activation energy of the disappearance of the layered structure was almost equal to the bulk viscous flow. This fact implies that the rate of disappearance of the layered structure was mainly dominated by the activation energy of bulk viscous flow rather than that of breaking the charge-dipole bond.
