Gold nanoparticles (NPs)/polypyrrole (PPy) bi-layer film was fabricated through a solution-based seeding process. The growth of the gold layer has been studied by the use of a field emission scanning electron microscope and UV–vis spectroscope. The results demonstrated that the PPy chains served as the reductant of chloroauric acid and the ligands to stabilize gold NPs. The resulting gold/PPy bi-layer film has a high conductivity of approximately 300 S cm−1 and can be fabricated into actuators because of its anistropic structure.
