“…Polystyrene sulfonic, itaconic, sulfosalicylic, phytic, dodecylbenzene sulfonic and the p-toluene sulfonic aciddoped PANI were directly polymerized via oxidation, then cleaned and dried. The resulting substances were incorporated with organic resin to produce corresponding composite coatings that offer both active protection and self-healing properties (Li et al, 2016;Najjar et al, 2018;Hao et al, 2017;Liu et al, 2022a;Silverman, 2002;Jin et al, 2020).…”

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.

“…GO has a large specific surface area and good dispersibility in water and excellent reactive activity and becomes a preferred material with high capacity and high selectivity. Therefore, in our research group, some students have prepared some new GO monolith for coatings, such as, the application of graphene-based adsorption materials has been expanded to the anticorrosive coating industry by some students (Jin et al, 2020b(Jin et al, , 2022(Jin et al, , 2023, showing their innovation and pioneering consciousness, indicating the positive role of innovative thinking in the technology research work.…”

The essence of education is to educate people, and the main goal of education is to educate on people how to think and make people not only have perfect personality, but also have strong learning ability. The teacher is the best person to complete education. Based on self-perception theory, the teacher guided students to finish the derivation of the Gibbs-Duhem (G-D) equation in order to strengthen the students' internal incentive. With a new establishment of partial molar quantity and set formula, students promoted their thinking ability and solidified internal incentive with a sense of achievement. The logical establishment process of the G-D equation was used to supplement this currently widely used derivation process by heuristic teaching method. The system conditions to which the G-D equation applied and the nature of its zero-degree homogeneous function were the key to understanding the derivation process. The derivation was carried out along the route of induction-deduction-induction, highlighting the training of thinking. Students' internal incentive not only strengthened their innovative ability, but also provided the conditions for their future success, which played a very important role in serving the society.

“…Similarly, PANi has been combined with graphene with the aim of increasing the dispersion of the graphene sheets to give corrosion protective coatings. These conducting polymer films have been formed through the electropolymerisation of aniline in the presence of well dispersed GO sheets to give protective coatings for aluminium alloys [147,148], iron [149] and a magnesium alloy [150]. There have also been a number of publications devoted to the incorporation of PANi and graphene into epoxy coatings [151][152][153][154][155][156] and in all these coatings good corrosion protection has been achieved.…”

Corrosion is a naturally occurring phenomenon and there is continuous interest in the development of new and more protective coatings or films that can be employed to prevent or minimise corrosion. In this review the corrosion protection afforded by two-dimensional graphene is described and discussed. Following a short introduction to corrosion, the application of graphene in the formulation of coatings and films is introduced. Initially, reduced graphene oxide (rGO) and metallic like graphene layers are reviewed, highlighting the issues with galvanic corrosion. Then the more successful graphene oxide (GO), functionalised GO and polymer grafted GO-modified coatings are introduced, where the functionalisation and grafting are tailored to optimise dispersion of graphene fillers. This is followed by rGO coupled with zinc rich coatings or conducting polymers, GO combined with sol-gels, layered double hydroxides or metal organic frameworks as protective coatings, where again the dispersion of the graphene sheets becomes important in the design of protective coatings. The role of graphene in the photocathodic protection of metals and alloys is briefly introduced, while graphene-like emerging materials, such as hexagonal boron nitride, h-BN, and graphitic carbon nitride, g-C3N4, are then highlighted.
