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.

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.

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.

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.

This study aims to provide one of the first research works that, using the constructs of the theory of planned behaviour (TPB), analysed the levels of purchase intention of organic products.

The study was quantitative with a correlational scope and a cross-sectional design. The study population consisted of 566 university millennials from Ecuador. The results were processed through the exploratory factor analysis (EFA), the confirmatory factor analysis (CFA) and the structural equation modelling (SEM).

The subjective attitudes and norms influence intentions to buy organic products. However, price mediated by perceived behavioural control reduces purchase intentions, while product availability does not.

This study is one of the first research works, based on the constructs of the TPB which was carried out to know if the attitudes and subjective norms of Ecuadorian university millennials, are related to their purchase intentions for organic products.
