Graphene-ion exchange polymer electric actuator as well as manufacturing method and application thereof

The invention discloses a graphene-ion exchange polymer electric actuator, wherein a perfluor ion exchange polymer is taken as a body film, conductive graphene films are fixed at two sides of the perfluor ion exchange polymer to serve as electrodes, and thus, an external electric signal input system is formed. The electric actuator has larger force/displacement output, has the mechanical output performance basically unattenuated under long-time work, and can work continuously under an air atmosphere for a long time without water supplement, therefore, the electric actuator can serve as a flexible electric actuator to drive miniature robots in intestinal tracts and blood vessels, wall-climbing robots, underwater robots, heart valve prosthesis, artificial skin, prosthetic vessels and the like.
