State of The Art on Development of Superhydrophobic Coatings for Corrosion in Marine Applications

Abstract

Owing to the water-repellence and anti-sticking properties, superhydrophobic technology has become a burgeoning subject of research area in innumerable fields. A great deal of literature articles covering corrosion control applications has been published. Howbeit, specific review focusing on superhydrophobic approach to ameliorate durability performance of coatings for corrosion protection in marine applications is still lacking. This literature first introduces the basic principles of superhydrophobicity, followed by the discussion of established approaches to fabricate superhydrophobic coatings. Besides that, the recent progress of superhydrophobic coatings intended for marine applications are also discussed. In addition, the challenges and future perspectives of anticorrosion coating for marine applications are presented. As a matter of fact, corrosion in marine environment is undeniably complex due to the diversity of seawater chemistry and the existence of biological organisms living in the ocean. Hence, this review served as ‘food for thought’ on the development of superhydrophobic coating by merging the coatings’ main features including corrosion protection and fouling mitigation in order to improve its sustainability and durability performance in the marine environment.
