Abstract

There are provided stretchable solid-state electroactive polymer actuators (SSEPA) using electroactive polymers that convert between electrical energy and mechanical energy and having solid-state polymer electrolytes. More particularly, there are provided electroactive polymer (EAP) compositions comprising: 15-60 wt. % of a film-forming polymer; 5-40 wt. % of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and 10-40 wt. % of a plasticizer, solid-state polymer electrolyte (SPE) compositions comprising: 20-60 wt. % of a plasticizer, 10-60 wt. % of a film-forming polymer and 5-25 wt. % of an ionizable salt. The use of these EAP and SPE compositions in electromechanical devices, such as solid-state actuators, generators, sensors, and other energy transducers in various applications are also disclosed.
