This study reports a smart composite film that mechanically responds to gases and restores its original shape. The highly elastic actuating composite film was prepared by mixing poly (vinylidene fluoride) (PVDF) polymer and flexible, crystalline organic cages. This work highlights the importance of designing smart materials at the molecular level to precisely control the response or reaction upon the introduction of different triggers.
The fabrication of smart materials, which can efficiently mimic biological systems through the introduction of soft components, is of great importance in the emerging fields of sensors and actuators. Herein, a smart composite film that can mechanically respond to vapors trigger then readily restores its original shape upon the removal of the stimuli is reported. This actuating composite film was prepared by mixing the highly elastic poly (vinylidene fluoride) (PVDF) polymer with the flexible and crystalline organic cages (Oba-cage) at variable concentrations. The mechanism of the mechanical response could be accurately recorded due to the ordered cage crystals. This work highlights the importance of designing smart materials at the molecular level to precisely control the response or reaction upon the introduction of different triggers, which can ultimately lead to a monumental leap in the field of soft robotics.
