Smart Protective Coatings for Corrosion Control

Overview of the latest research in advanced coatings for anticorrosion and the development of optimized surfaces with high anticorrosion ability

Smart Protective Coatings for Corrosion Control introduces the newest research developments in self-healing coatings, self-reporting coatings, and superhydrophobic coatings, reviewing corrosion processes and strategies, smart coatings for corrosion protection, techniques for synthesizing and applying smart coatings, different kinds of self-healing and self-reporting coatings activated by different environmental stimuli, and current and future trends of protective coatings for automotive, aerospace, marine, nuclear, oil/gas, and military applications.

This book also discusses new ideas in the field, such as the combination of self-healing and self-reporting properties, new techniques to study localized microscale electrochemical corrosion behavior, as well as atmospheric corrosion monitor technique to study the real-time protection behavior of coatings in different environments. The processes of coating degradation and metal corrosion are discussed in detail so that non-experts can gain a basic understanding of the corrosion protection techniques.

Written by two highly qualified academics with significant research experience in the field, Smart Protective Coatings for Corrosion Control includes information on:

• Coating preparation, filler preparation, surface characterization, macroscopic and microscopic electrochemical properties, and self-healing performance of self-healing coating systems under different environmental stimuli
• Photothermal conversion species such as graphene oxide, titanium nitride, and Fe₃O₄
• Different types of corrosion indicators, such as phenolphthalein, sulfosalicylic acid-modified carbon dots, and phenanthroline
• High-mobility polymer networks that endow a shape memory effect and allow coatings to recover their original shape and barrier properties
• Solutions to three corrosion conditions?room temperature immersion, alternating wet-dry, and outdoor atmospheric exposure conditions

Presenting the latest research in the field, Smart Protective Coatings for Corrosion Control is a practical and highly valuable reference on the subject for scientists, researchers, and students in diverse programs of study.
