“…The peak at 1290 cm −1 corresponds to π-electron delocalization resulting from the protonation of the polyaniline 46 . The absorption bands at 1108 cm −1 and 1048 cm −1 are attributed to the substituted benzene ring [47][48][49] .…”

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.

“…Ahmed and colleagues [5] discovered an ion-exchange copolymer made of formaldehyde, o-toluidine, and 8-hydroxyquinoline that has increased metal ion absorption capacity and functions as a superior ionexchanger for metal ion removal. Gurnule and associates produced a copolymer resin from 2-hydroxy acetophenone and adipamide with tioxane when Pb 2+ ions were utilised as an ion exchanger in place of Cu 2+ , Ni 2+ , Cd 2+ , Zn 2+ , and Fe 3+ ions [6][7]. Additionally, a few harmful bacteria and fungi were inhibited by the produced copolymer.…”

Composites are viewed as promising advanced materials because of their superior features, including enhanced flame retardancy, density, relatively large surface areas, strength and thermomechanical/optoelectronic/magnetic capabilities. 2-amino 6-nitrobenzothiazole, oxamide, and formaldehyde has been used for the synthesis of copolymerizing polycondensation technique, and newly synthesized copolymer with activated charcoal was used to synthesize its composite. Several physicochemical techniques, and Ultraviolet-visible, SEM, TGA, and FTIR techniques, have been utilized to illustrate the produced copolymer and its composite. The non-aqueous conductometric titration was used to determine the molecular weight of the 2-amino 6-nitrobenzothiazole-oxamide-formaldehyde copolymer.based on TGA data, thermal stability of the composite is higher than copolymer, possibly because there are more carbonized residues. Based on Ea values determined by Sharp-Wentworth and Freeman-Carroll technique for copolymer and its composite, it is observed that they are in good agreement with each other. It is abundantly obvious from the results of the sequence of reaction that the decomposition reaction roughly follows a first-order kinetics. The composite's higher surface area, porous makeup, and smaller particle size may have contributed to its superior performance. The copolymer and its composite have better heat stability.
