Dear Colleagues,

Hybrid coatings provide outstanding metallic protection in extreme environments for combining features of organic and inorganic materials that not only result in a remarkable barrier but also in improved mechanical, thermal, chemical and adhesion properties of coatings. In recent decades, the development of self-healing materials has added the possibility to regenerate hybrid coatings after failure, extending their service life. Self-healing coatings are able to repair or heal themselves by external intervention or autonomously, slowing or even stopping corrosion. When self-healing agents or systems such as corrosion inhibitors, chelation systems, microcapsules, interconnected vascular networks, shape-memory polymers, Diels–Alder or retro-Diels–Alder reactions (just to name a few) are properly integrated, a wide range of applications can be explored. Driven by the current demanding applications of smart materials, the design of self-healing organic–inorganic coatings must maintain the structural integrity of the hybrid matrix without compromising barrier and adhesion properties. In addition, to meet the requirements of a circular economy, eco-friendly materials are particularly sought out to replace the traditional ones. To this end, the unlimited possibilities for the design, synthesis, testing, and applications of high-performance anti-corrosion materials support this Special Issue to host papers in the following scope:

• Efficient methods to synthesize self-healing coatings
• Smart ecofriendly coatings for corrosion protection
• Green materials for effective corrosion inhibition
• New organic–inorganic hybrid systems for protection of metallic alloys
• Nanotechnology applied to organic-inorganic coatings
• Multifunctional polymer coatings
• Fitting and modeling of electrochemical measurements of self-healing coatings
• Water uptake calculations, prediction of performance and durability of hybrid coatings in extreme environments
• Self-healing mechanisms

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Coatings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
