Abstract: Conventional ionic polymer-metal composite (IPMC) employs Pt metal nanoparticles as electrodes and Nafion membrane as matrix film, and thus brings severe drawbacks of high electrode rigidity of electrode, an incompatibility between the matrix and the electrodes, and high cost of fabrication. This work used polyvinylpyrrolidone and polyvinyl oxide as the pore-forming agents and ionic liquid of [EMIm]·[BF4] as the plasticizer to prepare a highly porous flexible polyvinylidene fluoride (PVDF) matrix film. Physicochemical tests showed that PVDF matrix presented the high porosity of 26.3% and the low Young's modulus of 17.1 MPa. Using 3, 4-vinylenedioxythiophene (EDOT) as the monomer and FeCl3 as the catalyst, conductive PEDOT electrodes were anchored on both sides of the PVDF film by in-situ chemical deposition. After applying an AC electric field, a novel IPMC actuator using PEDOT electrode was obtained. In the condition of 0.1 Hz and 22 V, the resultant IPMC actuator showed continuous and stable driving behaviors with a maximum displacement output of 6.0 mm. With driven voltage or frequency changing, the displacement outputs subsequently changed, the IPMC actuator showing a good controllability.
