Multilayer Dielectric Elastomer Actuator with Enhanced Breakdown Strength via Regulating the Layer Thickness Ratio.

ABSTRACT: Dielectric elastomers, characterized by their rapid response speed, large actuated strain, and high energy density, presented significant advantages in the realm of flexible actuators. Enhancing the breakdown strength of dielectric elastomer actuators is crucial for ensuring actuated stability and achieving higher strain at elevated voltages. In this work, the theory of bilayer electric field redistribution was further investigated to guide the structural design of multilayer dielectric elastomers. The 11-layer (MWCNT-Ecoflex)/Ecoflex composites with tailorable insulating layer/polarization layer thickness ratios (r) were prepared by alternately stacking the insulating layer (Ecoflex) and the polarization layer (MWCNT-Ecoflex). We theoretically and experimentally demonstrated that i
