The marine environment presents one of the most aggressive and complex challenges tostructural materials, particularly mild steel, which remains the backbone of shipbuilding,offshore platforms, and coastal infrastructure. Conventional protective coatings, though widelyapplied, often fail under prolonged exposure to saline waters, oxygen-rich atmospheres, anddynamic mechanical stresses. This recurring issue has motivated researchers to exploreadvanced, bio-inspired strategies that not only inhibit corrosion but also enable coatings toautonomously repair damage.This book, Bio-Inspired Self-Healing Organic Coatings for Corrosion Protection of MarineMild Steel – A Critical Review, is conceived as a comprehensive synthesis of developments atthe intersection of corrosion science, organic inhibitors, biomimetic design, and smartmaterials engineering. It critically examines both fundamental mechanisms and appliedtechnologies, ranging from lotus-leaf hydrophobicity and mussel-inspired adhesion tomicrocapsule-based self-healing and stimuli-responsive release systems. By bridging academicresearch with industrial practices, the work aims to provide a structured roadmap for scientists,engineers, and policymakers engaged in marine corrosion protection.The chapters are organized to progressively build understanding—from electrochemicalfundamentals and inhibitor chemistry to advanced testing protocols and industry case studies.Special emphasis is placed on environmental considerations, scalability, and regulatoryframeworks, ensuring that the discussion remains relevant to both laboratory innovation andreal-world deployment. Future trends such as nanomaterials, AI-guided design, and greenchemistry are highlighted to inspire sustainable pathways for next-generation coatings.This book is the outcome of years of engagement with corrosion science, materials engineering,and digital workflow optimization. I am deeply indebted to my mentors, colleagues, andresearch collaborators whose insights shaped the perspectives presented here. I alsoacknowledge the support of academic institutions and industry partners who continue toadvance the field of protective coatings.It is my hope that this critical review will serve as both a reference and a catalyst—encouragingfurther innovation in bio-inspired self-healing coatings and contributing to the long-termdurability of marine infrastructure.
