Corrosion, Biofouling, and Hydrodynamic Behavior as a Function of Topography and Composition of Superhydrophobic Coatings
Abstract
Corrosion, Biofouling, and Hydrodynamic Behavior as a Function of Topography and Composition of Superhydrophobic CoatingsCorrosion, Biofouling, and Hydrodynamic Behavior as a Function of Topography and Composition of Superhydrophobic Coatings. For effective naval systems, materials that can enhance performance and reduce downtime are critical. The proposed research is intended to address this need by understanding the performance characteristics and behavior of superhydrophobic coatings at a fundamental level. Superhydrophobic (SH) coatings have the potential to reduce corrosion and the associated downtime. They also have the potential to reduce biofouling by preventing adhesion of biofilms and consequently drag, leading to enhanced performance. The proposed work is to build off the current UML/Shenkar durable superhydrophobic coating system for use in corrosion protection, reduced biofouling and improved hydrodynamic behavior. The work will evaluate the corrosion protection of the current coating systems, modify the coating formulation, and explore robust topography characterization techniques to provide insight on the role of topography in superhydrophobicity and corrosion protection. The corrosion protection behavior of the coatings will be evaluated. The coatings and topography studies will be expanded to biofouling and hydrodynamic behavior to broaden the role of superhydrophobicity and surface topography on nautical performance. We also will explore the creation of superhydrophobic coatings using a more viscous thermoplastic binder system to understand the role (and ultimately control) of interfacial behavior in the creation of superhydrophobic surfaces. The thermoplastic coatings will be evaluated for corrosion protection and the topography measured. Then, the work will be widened to systems with pigment and UV stabilizer additives, which are more realistic of current CARC coating systems. In addition to corrosion protection, the biofouling and hydrodynamic behavior of the thermoplastic systems will be evaluated.
