Detailed descriptions of electrochemical grafting PEDOT thin film on IPMC electrode surface, X-ray photoelectron spectroscope analyses, and detection of sheet resistances for all IPMCs were shown in Supplementary Data 1–3, observations of contact angle (CA) measurements, partial morphological characterizations of PEDOT coated IPMCs vs electrografting time, and IPMC performance under varying step voltages were shown in Supplementary Data 4–6. The following is Supplementary data to this article: Dongjie Guo received a PhD in Materials Chemistry from the Nanjing University in 2006 under the supervision of Prof. Dr. Shoujun Xiao. Then, he was a post-doc in 2008–2009 and a visitor scholar in 2016–2017 at Department of Mechanical Engineering at University of Colorado (Boulder). He worked at Nanjing University of Aeronautics and Astronautics as an associate professor in 2008 specializing in fabrications of gecko biomimic adhesive and artificial muscle. He was a special professor at State Laboratory of Surface & Interface in Zhengzhou University of Light Industry in 2014, specializing in fabrications and applications of the electric active polymer (EAP) such as IPMC, DEP, and CP. Xinjie Wang received a PhD in mechanical and electronic engineering from Huazhong University of Science and Technology in 2005 under the supervision of Prof. Peigen Li, academician of the Chinese academy of engineering. Her majors are mechanical and electrical system dynamics and control, industrial robot control. She won the National Science and Technology Progress Award at 2018, First Prize of Natural Science of the Ministry of Education at 2016. She is now a member of the National Institute of Mechanical and Electrical Products Development of the National Institute of Higher Education, and Managing Director of the Association for the Development of Mechanical in Henan province.

N2 - Current ionic exchange polymer metal composite (IPMC) has always been associated with short stable working time due to the presence of severely electrode fatigue and water loss, which limits its wide-spread applications. To address this problem, a facile and effective strategy has been proposed to repair the IPMC by electrografting a conductive, flexible polymer of Poly(ethylenedioxythiophene) (PEDOT) on IPMC electrode surface in this study. The investigation of physiochemical properties of PEDOT coating revealed that EDOT molecules could fill into the electrode cracks generated from fatigue and then were polymerized into PEDOT with a linear conjugation structure. The PEDOT-coated electrodes exhibited significantly improved conductivity and effectively reduced water loss. The PEDOT coating can repair the common actuation defects of the used IPMC actuators, such as asymmetrical actuation and torsional deformations. Moreover, the introduction of PEDOT coating apparently improved electromechanical properties by increasing swing angles and displacements, and prolonging the stable working time to more than 1000sec without fatigue.
