Preparation method and application of a dual-stimulus responsive driver film

By preparing an azobenzene polymer solution and casting it into a dual-stimulus responsive actuator film, the limitations of a single-stimulus responsive actuator were overcome, achieving a biomimetic driving effect under dual stimulation of light and moisture, which can be applied to intelligent biomimetic devices.

Abstract

The application discloses a preparation method and application of a double-stimulus-responsive driver film, and belongs to the field of double drivers. The application takes azobenzene monomer and isocyanate as raw materials, obtains a polymer solution through a step-by-step addition polymerization reaction, and pours the polymer solution in a polytetrafluoroethylene mold to obtain a driver film with light / humidity double-stimulus responsiveness. Due to the reversible molecular configuration transformation of azobenzene and the great difference in film hygroscopicity, the driver film has a quick and sensitive reversible bending deformation behavior under light and humidity stimulation, and has important application value in the field of intelligent bionics.
