Recently, plasticized nonionic polyvinyl chloride (PVC) gels are conducting for soft actuators like micro lens and artificial muscle applications, because PVC gels are highly transparent, high ductility, and good dielectric materials. However, existing PVC gel plasticized by large amounts external plasticizers suffer from poor electric performance because of their poor ductility and leakage current. In this study, we introduced synergistic plasticization of PVC gel with PVC and PVC-co-VA (Polyvinylchloride co vinyl acetate) and Dibutyl adipate. The PVC gels were characterized using X-ray diffraction (XRD) analysis, FTIR spectroscopy, ultraviolet-visible spectroscopy, dielectric constant analysis, tensile test. Synergistic plasticization of PVC gel can be achieved high transparent, high dielectric constant, high ductility and lower leakage current with small amount of DBA than only externally plasticized PVC gel. |
