When the bilayer is Subject to solvent vapor, the strain is generated in the polymer layer that is confined by the substrate and the metal capping layer. An increase in the strain induces the development of the stress in the bilayer to deform the lower polymer layer perpendicularly to the surface of the bilayer. Isotropic Surface wave patterns results from the stress relaxation. the wave number of the patterns shows a characteristic temporal dependency on the swelling time, such that k(m)(t) similar to t(-1/8). This temporal evolution accompanied by the morphological dynamics gives smaller value of the growth rate of the characteristic wavelength than that of the case of swelling of gel.
