A Light‐Activated Polymer Composite Enables On‐Demand Photocontrolled Motion: Transportation at the Liquid/Air Interface

Swimmers at liquid/air interfaces have drawn enormous attention because of their potential applications. Described herein is one novel light‐driven swimmer based on a bimorph composite structure of a photoresponsive liquid‐crystalline polymer network and a commercially available polyimide (Kapton). The motion of the swimmer can be controlled by photoirradiation. The bilayer‐structured film shows quickly photoinduced bending towards the Kapton...
