主　　题：i-EAP PEO electromechanical response model 

摘      要：The characteristics of the electromechanical response observed in an ionic-electroactive polymer(i-EAP)are represented by the time(t)dependence of its bending actuation(y).The electromechanical response of a typical i-EAP—poly(ethylene oxide)(PEO)doped with lithium perchlorate(LP)—is *** shortcomings of all existing models describing the electromechanical response obtained in i-EAPs are discussed.A more reasonable model:y=y_(max)^(e-T/t)is introduced to characterize this time dependence for all *** advantages and correctness of this model are confirmed using results obtained in PEO-LP actuators with different LP contents and at different *** applicability and universality of this model are validated using the reported results obtained from two different i-EAPs:one is Flemion and the other is polypyrrole actuators.
