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.
