Based on the concept of biomimetics and combined with wet chemical processing, our laboratory has successfully developed a novel wet-fabrication method for producing large-area and highly ordered wrinkle structures. The wrinkle morphology primarily originates from a bilayer system consisting of a soft substrate coated with a thin rigid layer. When environmental changes induce a mismatch in mechanical stress between the two layers, surface instabilities occur, leading to the formation of wrinkle patterns. By adjusting the solution concentration and the crosslinking degree of the soft layer (PDMS silicone elastomer), the wavelength, amplitude, and morphology of the wrinkles can be precisely controlled. This wet-fabrication strategy is versatile and can be applied to a variety of material combinations to generate different wrinkled structures. The compositional flexibility of this system allows the tuning of physicochemical properties through hybrid material designs, such as polymer/ceramic, polymer/metal, and polymer/epoxy composites, thereby forming diverse and multifunctional highly ordered wrinkled hybrid materials. Based on this wrinkle-generation technology, our laboratory has successfully developed several promising industrial applications, including dry adhesive surfaces, superhydrophobic coatings, and antifouling/anticorrosion coatings.
