Summary: This study investigates the influence of different layers in electrochemical yarn actuators using various electrochemical methods. It is found that selecting appropriate electrochemical conditions (such as an applied potential of +0.8 V) is crucial in obtaining high-quality polypyrrole. Additionally, the underlying layer of PEDOT:PSS affects the electrochemical polymerization conditions and can undergo parallel redox reactions, such as oxidation or electrochemical degradation, which impact the electropolymerized polypyrrole.
