Presentation of Yuwei WU, PhD student and her 6 months internship at the FZU, supervisor David Vokoun

Seminar  of Functional Materials and Composites "FMC"   on Thursday, June 8, 2023, at 10:00 a.m. in meeting room 117 (main building)


Living creatures in nature exhibit diverse and intricate movements featuring flexibility, resilience, robustness, and efficiency. Undoubtedly, muscles play a vital role in performing their daily activities. As a consequence of mimicking biological muscles, polyvinyl chloride (PVC) gel, an electroactive polymer, presents a contraction-relaxation behavior under the action of an electric field. With the advantages of large actuation strain and stress, excellent flexibility and transparency, fast response speed and moderate actuating voltage, PVC gel has been proved great potential in fields such as soft robotics, assisted rehabilitation systems, electromechanical devices, and optical lenses. In order to clarify the thermal properties and internal structure of the material, a series of experiments were carried out and characterized by TGA, DSC, DMA, FTIR and XRD.
