Dynamic metal patterns of wrinkles based on photosensitive layers

Self-adaptive wrinkling modes of a metal/PAN/PDMS multilayer were demonstrated based on the theoretical studies and observed, which will pave the pathway for spontaneously regulating functional homogeneous metal surfaces. Photodynamically regulating the underlying PAN/PDMS bilayer will promote the development of chemical reprogrammable techniques and the physical dynamic adjustability of metal-patterned surfaces to realize smart optical materials.
