abstract = "Carbon nanofiber (CNF) / Polypyrrole (PPy) composite material film was fabricated by an electrochemical method. The flexibility of CNF/PPy has been improved much better than the same material what was fabricated by a physical method. Pure PPy films were also fabricated by an electrochemical method for comparison. Several SEM images were taken at two locations (electrode side and solution side) of the sample. Electrical conductivity of the composite film was measured by using a four-probe method. The conductivity of the pure PPy film 0.013 cm thick was 79.33 S/cm. The CNF/PPy composite film with the thickness of 0.017 cm showed a conductivity of 129.33 S/cm, which is much higher than that of the pure PPy film. The actuation strains were tested. Strains of 11.2\% and 14.7\% were given by CNF/PPy film and pure PPy film, respectively. The good conductivity and high actuation strain of CNF/PPy composites show the improved potential for developing the materials for a small muscle-like actuator.",
