    Universal techniques for material surface modification are required, since material surfaces have a strong influence on their properties, e.g., adhesion, electrical properties, and biocompatibilities. Recently, catecholic polymers that are inspired from nature have been of interest in many fields, because of their adhesion property onto various types of materials. In this review, we focus on catecholic polymers, i.e., polydopamine, urushi, and plant polyphenol-based films, which have emerged as new methods for universal surface-modification. We also describe the preparation of polydopamine particles and their use as a structural color material. We hope that these novel methods based on catecholic polymers for the fabrication of functional surfaces and materials will contribute to the progress of many processes.

    Basic corrosion theory which has been developed based on electrochemistry is described with focusing the potential-pH diagram and the electrode kinetics to understand the corrosion process of iron and steel. The importance of oxygen reduction and inhibitive function of corrosion film on the steel surface in neutral solution is pointed out for understanding corrosion phenomena experienced in daily life. Close relationship between air pollution and steel corrosion is demonstrated. Development of weathering steel contributes for improving the atmospheric corrosion. Highly protective property of the passive film on stainless steel is described.
