Soft actuators with large deformation and high output force in response to multi-stimuli are highly demanded for the development of biomimetic applications. Based on this bilayer actuator, diversely biomimetic motions including human hand movement are realized, revealing its potential application in soft robotics, artificial muscles, wearable electronics, and biomedical devices. In this study, we prepared a bilayer actuator composed of thiourea network film with internal photo-generated fluorine (PGF) and fluorine amplification molecules is fabricated by a simple and fast method. This actuator produces large deformation, and dual-stimuli response, owing to the volume contraction of thiourea film with the absorption of fluorine, and the kosmotropic effect. The novel functional actuator is especially suitable for research on improving the anion sensitivity of soft actuators applied with a chemical amplification reaction of anions.
