Actuator Based on a Dielectric Elastomer with Quartz as a Filler for Vacuum Technology

Abstract

Modern equipment requires precise movement of objects both at atmospheric pressure and in vacuum conditions. Moreover, vacuum equipment is subjected to a number of external disturbances that adversely affect the manufacturing process and have a direct impact on the quality of manufactured products. A promising development in this area is actuators based on dielectric elastomers, characterized by a short reaction time (milliseconds) and a simple and cheap implementation. Successful implementation depends on an understanding of its behavior and properties, depending on the choice of matrix and filler materials. Most often, expensive barium titanate is used as a filler. This paper discusses the use of quartz as a cheaper filler.

Effect of the spin crossover filler concentration on the performance of composite bilayer actuators

“…The study of the filler concentration is obviously a key parameter because it allows to modulate not only the actuating properties, but also, in certain cases, the thermomechanical and/or the electrical properties of the active layer. For example, it was shown that the increase of quartz concentration in a dielectric elastomer can enhance the dielectric properties, resulting in an increased actuation amplitude [28]. Similar improvement was obtained while increasing the magnetic filler concentration in magnetic polymer composites, resulting also in the increase of the material stiffness [29].…”
