Poly(dimethylsiloxane)/Poly(vinyl alcohol) Composite Films with Low Initial Modulus and High Dielectric Constant for Electrical Actuators |
| 초록 |
Electrical actuation of elastomer films strongly depends on both their dielectric constant and initial modulus. In this presentation, we introduce a poly(dimethylsiloxane) (PDMS)/poly(vinyl alcohol) (PVA) composite film with high dielectric and low mechanical properties for large actuation. We synthesized high molecular weight poly(dimethylsiloxane-co-methylvinylsiloxane) with ca. 15.0ⅹ104 of Mn for obtaining tough composite films UV-cured from the PDMS solution in vinyl acetate. For saponification, the UV-crosslinked films were chemically treated in a 10 wt% sodium hydroxide solution in water. Dielectric constant of the composite films was increased after saponification. The UV-crosslinked film was getting tougher, as well. We are going to discuss in detail the physical property variations with the saponification and the possibility of utilizing the composite film as an electrically actuated elastomer. |
