Abstract: A film comprises an elastomeric or soft polymer substrate that is capable of converting light to heat a second layer comprising a hydrophilic polymer and nanosheets of layered inorganic material dispersed in the hydrophilic polymer. The substrate can comprise a photothermal particle. The film can be used in a method by irradiating the film to cause wrinkles and optionally further exposing the film to moisture with optional drying.

Abstract: Disclosed is a stretchable, three-dimensional tubular structure formed due to processing-induced wrinkles to result in a platform for stretchable interactive electronics. The three-dimensional tubular structure is fabricated simply by releasing a pre-stretched two-dimensional film-substrate precursor, and the resulting wrinkled surface shows a strong directional dependence that drives the tube formation.

Abstract: Disclosed herein is a thermal radiation modulation system comprising a first low emissivity layer comprising a plurality of distributed, strain-dependent cracks, the first low emissivity layer comprising a first polymer composite layer and a first mirror-like metal layer with low emissivity covering a surface of the first polymer composite layer; a first elastomer layer bonded to the first low emissivity layer opposite to the mirror-like metal layer; and optionally a first stretchable heater, the first stretchable heater is attached to the first elastomer layer opposite to the first low emissivity layer, wherein a top surface of the first low emissivity layer comprising the mirror-like metal layer has a lower emissivity relative to the first elastomer layer. Methods of making and use of the system are further described.
