“…The characteristic absorption peak of stretching mode of the N-H bond appears at 3217 cm −1 , indicating the existence of secondary amine unit of PANI on the IPMC surface 44 . The peaks at 1558 cm -1 and 1484 cm −1 suggest the non-symmetric vibration of C-H bonds in the quinoid rings and C=C stretching mode of benzenoid rings of the partially reduced form of PANI, respectively [44][45][46] . The peak at 1290 cm −1 corresponds to π-electron delocalization resulting from the protonation of the polyaniline 46 .…”

Ionic polymer-metal composites (IPMC) are typical electromechanical transducing materials suitable for use as soft actuators, bioinspired artificial muscles and sensors. However, IPMC produced with platinum films has the great disadvantage of the large number of cracks and wrinkles, which reduce the performance of the electrode. Polyaniline (PANI) is a promising conductive polymer that can address this issue, especially when it is electropolymerized on the platinum surface. An IPMC/PANI actuator was developed by potentiostatic electropolymerization of PANI at 0.9 V in 0.1 M and 0.3 M aniline solution. The characterization revealed that PANI is preferentially electropolymerized in the platinum film cracks and improve the electronic conduction mechanisms, which is not reported so far. The maximum tip displacement of the IPMC/PANI under 5 V was 8.3 mm, while for the IPMC was equal 5.2 mm. These results provide a simple and effective method to repair IPMCs and enhance their electromechanical performances.
