The main objective of this review is to describe some of the important topics related to the use of marine and protective coatings for anticorrosive purposes. In this context, “protective” refers to coatings for containers, offshore constructions, wind turbines, storage tanks, bridges, rail cars, and petrochemical plants while “marine” refers to coatings for ballast tanks, cargo holds and cargo tanks, decks, and engine rooms on ships. The review aims at providing a thorough picture of state-of-the-art in anticorrosive coatings systems. International and national legislation aiming at reducing the emission of volatile organic compounds (VOCs) have caused significant changes in the anticorrosive coating industry. The requirement for new VOC-compliant coating technologies means that coating manufacturers can no longer rely on the extensive track record of their time-served products to convince consumers of their suitability for use. An important aspect in the development of new VOC-compliant, high-performance anticorrosive coating systems is a thorough knowledge of the components in anticorrosive coatings, their interactions, their advantages and limitations, as well as a detailed knowledge on the failure modes of anticorrosive coatings. This review, which mainly deals with European experience and practice, includes a description of the different environments an anticorrosive coating system may encounter during service. In addition, examples of test methods and standards for determination of the performance and durability of anticorrosive coatings have been included. The different types of anticorrosive coatings are presented, and the most widely applied generic types of binders and pigments in anticorrosive coatings are listed and described. Furthermore, the protective mechanisms of barrier, sacrificial, and inhibitive coatings are outlined. In the past decades, several alternatives to organic solvent-borne coatings have reached the commercial market. This review also presents some of these technologies and discusses some of their advantages and limitations. Finally, some of the mechanisms leading to degradation and failure of organic coating systems are described, and the reported types of adhesion loss are discussed.

Self-healing: A new paradigm in materials design

Delivery of the Smart Grid is a topic of considerable interest within the power industry in general, and the IEEE specifically. This paper presents the smart grid landscape as seen by the IEEE Dielectrics and Electrical Insulation Society (DEIS) Technical Committee on Smart Grids. We define the various facets of smart grid technology, and present an examination of the impacts on dielectrics within power assets. Based on the trajectory of current research in the field, we identify the implications for asset owners and operators at both the device level and the systems level. The paper concludes by identifying areas of dielectrics and insulation research required to fully realize the smart grid concept. The work of the DEIS is fundamental to achieving the goals of a more active, self-managing grid.

The impact of smart grid technology on dielectrics and electrical insulation

This chapter mainly discusses reversible cross-linking polymer-based self-healing materials, which will help to eliminate hidden hazards, prolong the service life, and extend the application area of polymeric materials. The chapter first reviews automatically self-healing polymers with embedded microencapsulated healing agents. The chapter then discusses cross-linked healable polymeric materials based on reversible noncovalent bonds, including hydrogen bonds, π–π stacking interaction, and metal–ligand coordination. Finally, the chapter reviews cross-linked healable polymeric materials containing reversible covalent bonds (Diels–Alder adducts).

Reversible cross-linking polymer-based self-healing materials

Role of Design in Corrosion and Corrosion Prevention

Recent studies in the polymer and polymer-composite literature have focused on technology to facilitate self-healing of epoxy polymers that crack on aging, for which no outside intervention is necessary. The self-healing process is referred to as autonomic healing. The concept of self-healing is not new, but healing without the necessity of outside action to facilitate the process is novel. The state of the technology as of the time of this study is reviewed, and the suitability for utility applications is the focus of this paper.
