CUSTOMIZED POLYMERIC ACTUATORS DRIVEN BY ACETONE

Abstract

Actuators, materials capable of shape alteration in response to environmental changes, are vital for various mechanical tasks. Polymer-based actuators, known for their sensitivity and mechanical advantages, often utilize bending deformation in applications like mobile robots and energy conversion. However, comprehensive studies on bending behavior are lacking. To address this, we developed solvent-responsive PVDF-HFP films, studying their swelling laws and bending with external stimuli. Collaborating with A*star IHPC, we explored size effects on bending behavior through simulations. Further, we crafted a unique tower-shaped PVDF-HFP actuator exhibiting shape transitions and underwater adhesion. This multifunctional actuator, with potential in information transmission, water locomotion, and soft robotics, opens possibilities in sensory technologies and drug delivery systems. Its circular-to-polygonal morphing capability suggests a promising future in diverse fields.
