Dielectric material for polymeric actuator, and polymeric actuator using the same
Abstract:
A dielectric material for a polymeric actuator having a moveable part of the polymeric actuator driven by an electric field, the dielectric material containing a block copolymer (A) having a microphase-separated structure including a polymer block (B1) and a polymer block (B2), both of which are immiscible with each other. A main compositional unit in both of the polymer block (B1) and the polymer block (B2) is a (meth)acrylic ester unit, the polymer block (B1) having an alpha-dispersion temperature of 70° C. or more, and the polymer block (B2) having an alpha-dispersion temperature of 25° C. or less. The polymeric actuator provides the dielectric material between electrodes.
