Corrosion protection of metals and alloys relies on different protective measures including the use of organic coatings. Nowadays, there is a plethora of corrosion resistant coatings available based on complex formulations of film-forming agents, pigments and extenders, additives and plasticizers, targeting high-performance and durability of structures exposed to harsh conditions.

Neverthless, coating degradation upon exposure can occur. The ingress of water and electrolyte species from the surrounding environment through pores, cracks and other defects can result in the loss of corrosion protection of primer coatings. In the case of topcoat layers, additional exposure to UV radiation, oxygen and temperature can lead to degradation of the polymer matrix. Therefore, research into the corrosion or degradation of coatings is vital to their application.

For the last two decades, novel materials such as nano oxide particles, layered double hydroxides, graphene-based materials, polymeric capsules and spheres, have been used for developing corrosion-resistant coatings. Additionally, modified film-forming agents were used to improve barrier property or anti-aging ability of the coatings. The combination of these materials also produces multi-functional coatings, in order to broaden the application fields.

Although great progress has been made in the development and application of the above-mentioned novel materials, the derived materials and modifications are needed for developing next-generation protective coatings. Regarding the use of novel materials, some problems should be addressed, i.e., the compatibility between the novel materials and resin matrix, and the impact of the novel materials on overall properties of the coatings. In addition, new characterization techniques as well as approaches for the study of corrosion and assessment of coatings properties are also important issues.

This Research Topic stems from the need to develop novel materials for protective coatings and study the effect of these materials for improving the corrosion resistance and durability. The general aim is to gain insight into the protective mechanism of coatings using novel materials.

We welcome the submission of original research articles as well as review articles on the synthesis, modification and assessment of novel materials for the development of protective coatings. Fundamental studies on the corrosion and degradation behaviour of the coatings are also encouraged.
