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.
