“…PANI fibers can be produced by directly polymerizing aniline at the boundary solution of immiscible aqueous and organic liquids (Yao et al, 2020). Siva et al (2020) generated a homogenous solution by combining dodecylbenzene sulfonic acid, APS and aniline in the aqueous phase and the organic phase. Chemical oxidation polymerization resulted in the generation of PANI fibers doped with dodecylbenzene sulfonic acid (see Figure 3).…”

Purpose Polyaniline (PANI) has garnered attention for its potential applications in anticorrosion fields because of its unique properties. Satisfactory outcomes have been achieved when using PANI as a functional filler in organic coatings. More recently, research has extensively explored PANI-based organic coatings with self-healing properties. The purpose of this paper is to provide a summary of the active agents, methods and mechanisms involved in the self-healing of organic coatings. Design/methodology/approach This study uses specific doped acids and metal corrosion inhibitors as active and self-healing agents to modify PANI using the methods of oxidation polymerization, template synthesis, nanosheet carrier and nanocontainer loading methods. The anticorrosion performance of the coatings is evaluated using EIS, LEIS and salt spray tests. Findings Specific doped acids and metal corrosion inhibitors are used as active agents to modify PANI and confer self-healing properties to the coatings. The coatings’ active protection mechanism encompasses PANI’s own passivation ability, the adsorption of active agents and the creation of insoluble compounds or complexes. Originality/value This paper summarizes the active agents used to modify PANI, the procedures used for modification and the self-healing mechanism of the composite coatings. It also proposes future directions for developing PANI organic coatings with self-healing capabilities. The summaries and proposals presented may facilitate large-scale production of the PANI organic coatings, which exhibit outstanding anticorrosion competence and self-healing properties.

“…101 Electrochemical impedance spectroscopy (EIS) is a highly sensitive non-destructive analytical technique, used to study a variety of physical and electrochemical properties, including capacitance, electron transfer rate constants, diffusion coefficients, adsorption mechanisms, and charge transfer resistances. 148,161 Based on EIS measurements, it has been concluded that the star-shaped morphology facilitates ion diffusion compared to the linear structure, which in turn results in a substantially lower intrinsic resistance. 47,131 The resistance values are calculated using Zview software: 173.40 Ω for linear NH 2 -(ANI) 4 -COOH, 50.39 Ω for para-bi-(ANI) 4 -COOH, 37.74 Ω for meta-bi-(ANI) 4 -COOH, and 33.68 Ω Tri-(ANI) 4 -COOH films.…”
