Abstract
Dielectric elastomer composites are widely used electromechanical actuators. Compounding of dielectric elastomers with electroceramics helps to decrease the required electric field. In this work, silicone rubber was compounded with Lead- Zirconate-Titanate (PZT) electroceramic powder by the help of a silane coupling agent for better compatibility between organic ceramic and inorganic polymer. Modified PZT was added to silicone rubber with variable amount to study the effect of ceramic concentration on composites properties. Morphology of the composites was characterized by scanning electron microscopy, mechanical properties of the samples were studied by uniaxial tension, and their dielectric properties were compared through dielectric measurements. The results showed that at about 10 wt% of PZT loading dielectric permittivity is higher for this composite compared to those for composites with lower or even higher loading of PZT.
