成果简介	NOVELTY - Developing a wrinkled bi-layer material involves (i) preparing a polydimethylsiloxane (PDMS) substrate by mixing a predefined concentration of liquid PDMS base with 1 pts. wt. curing agent to form a mixture; (ii) desiccating the mixture to remove bubbles; (iii) pouring the mixture onto a silicon mold; (iv) curing the mixture at a predefined temperature for a predefined time period; peeling a layer of cured PDMS substrate containing ridges from the silicon mold; (v) depositing a thin film of a material onto the layer of cured PDMS substrate via physically; (vi) subjecting the thin film deposited over the layer of cured PDMS substrate to thermal processing to create a wrinkled surface of the thin film, where the thermal processing involves heating and subsequent cooling down to a room temperature. USE - Method for developing a wrinkled bi-layer material for use as visible camouflage, tunable diffraction gratings, tunable optical diffusers, device for increasing out-coupling efficiency of encapsulated light sources and photovoltaics, flexible and washable reflective displays, and mechanochromic sensors. ADVANTAGE - The method is effective and has high versatility, and the method is compatible with a wide range of materials, including chalcogenides, metals, and polymers, resulting in well-ordered sinusoidal wrinkles.
