Paper Abstract
Much attention has been given to ionic electroactive devices constructed using conducting polymers due to their low
voltage requirements, high strain, and similarities to natural muscle. However, the time response and output force of
conducting polymer actuators has always been a limiting factor in their implementation. In this study, we report on
a processing technique and parametric optimization for multilayer polypyrrole-gold-polyvinylidene fluoride (PPy-
Au-PVDF) composite actuators that have the possibility of overcoming the prior problems. These actuators are
operable in air, have faster time response, and are projected to generate higher force compared to that of
conventional conducting polymer actuators. These improvements are made possible due to the improvement in
processing conditions and novel multilayer geometry of the actuators. A five layer PPy-Au-PVDF-Au-PPy actuator
operating in air with 0.5M KCl electrolyte was shown to generate deflections up to 90% of the actuator length at a
rate of 50% per second.
