摘要 Ripple structures have been used in electronics, optics, magnetics, chemistry, and structural coloration. Commonly used methods for manufacturing large‐area polymeric thin films with ripple structures include mechanical buckling, fracture‐induced structures (FISs), and laser induced periodic surface structures (LIPSS). In this study, we further proposed two FIS methods to fabricate easily and quickly large area self‐generated nonlinear and linear micro‐ripple structures. The initially featureless polystyrene film was effectively bonded between two rigid JIS SKD 61 (SKD61) steel cylinders and two soft PET films and then peeled off, the latter was cryogenically treated in liquid nitrogen before peeling off, the polystyrene film fractured into two complementary sets of nonlinear and linear micro‐ripple structures of the same period. The SKD61/ polystyrene (PS)/SKD61 sandwiched film used a slower peeling velocity and a thinner polystyrene film, which could fabricate a more complete and shorter period nonlinear wave structure. As the PET/PS/PET sandwiched film was cryogenically processed, it could produce a steeper waveform and flat valley linear ripple structures without cracks and ripple dislocations, with a period about 37 μm and an area about 300 cm2.
