A generic experimental procedure is presented in this work to enhance
the electrical responses of polydimethylsiloxane (PDMS) through
incorporation of conducting polymer nanowires, while maintaining the
desirable mechanical flexibility of PDMS. The conducting polypyrrole

Experimental study on the dielectric properties of polyacrylate dielectric elastomer

The dielectric constant of elastomeric dielectric material is an
essential physical parameter, whose value may affect the
electromechanical deformation of a dielectric elastomer actuator. Since
the dielectric constant is influenced by several external factors as
reported before, and no certain value has been confirmed to our
knowledge, in the present paper, on the basis of systematical comparison
of recent past literature, we conducted extensive works on the
measurement of dielectric properties of VHB films, involving five
influencing factors: prestretch (both equal and unequal biaxial),
electrical frequency, electrode material, stress relaxation time and
temperature. Experimental results directly show that the dielectric
