Organic coatings have shown an impressive evolution in recent years, both scientifically and technologically. Nanotechnology and surface science allows the development of multifunctional materials combining different properties, such as corrosion protective actions, aesthetical functions, hydrophobic properties, and self-healing ability. In addition, recent advances in experimental techniques and the attention to environmental issues are pushing to develop new systems, joining advanced performance with high sustainability. The aim of this Special Issue is to provide an update on the most advanced research in this area, showing the innovation trends and promoting further research for better properties of new coatings materials.
