Special Issue Information

Dear Colleagues,

Corrosion, by definition, is the deterioration of a metal by chemical or electrochemical interactions with the surrounding environment, representing significant economic losses in industrialized countries. Therefore, it is important to develop strategies to prevent and/or minimize damages caused by corrosion, whether being in aeronautical, industrial, or biomedical applications. Among the various existing methods to avoid or prevent metal degradation, protective coatings and corrosion inhibitors are the most common, playing an important role in the protection against corrosion processes.

Corrosion inhibitors have excellent anti-corrosive properties; however, concerns have been raised about their toxicity and significant damage to the environment. In particular, there is greater concern when used on biomedical-grade metals. This, along with increasingly stringent environmental regulations, has progressively led to the replacement of toxic corrosion inhibitors with non-hazardous ones. Therefore, non-toxic and eco-friendly natural corrosion inhibitors have been extensively researched in recent years in an attempt to respond to increased environmental awareness.

The aim of this Special Issue of Materials is to provide original research and critical reviews on eco-friendly corrosion inhibitors. Areas of interest include the development, characterization, and application of eco-friendly corrosion inhibitors and coatings for the corrosion protection of metals used in different applications.

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. Materials is an international peer-reviewed open access semimonthly 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 2300 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.

Long-term corrosion protection of metals might be provided by nanocomposite coatings having synergistic qualities. In this perspective, rapeseed oil-based polyurethane (ROPU) and nanocomposites with calcium and magnesium ions were designed. The structure of these nanocomposites was established through Fourier-transform infrared spectroscopy (FT-IR). The morphological studies were carried out using scanning electron microscopy (SEM) as well as transmission electron microscopy (TEM). Their thermal characteristics were studied using thermogravimetric analysis (TGA). Electrochemical experiments were applied for the assessment of the corrosion inhibition performance of these coatings in 3.5 wt. % NaCl solution for 7 days. After completion of the test, the results revealed a very low icorr value of 7.73 × 10−10 A cm−2, a low corrosion rate of 8.342 × 10−5 mpy, impedance 1.0 × 107 Ω cm2, and phase angle (approx 90°). These findings demonstrated that nanocomposite coatings outperformed ordinary ROPU and other published methods in terms of anticorrosive activity. The excellent anti-corrosive characteristic of the suggested nanocomposite coatings opens up new possibilities for the creation of advanced high-performance coatings for a variety of metal industries.
