Direct patterning of drag-reducing patterns within Naval-relevant coatings

Abstract

Drag on Naval vessels comes with significant monetary and capability costs for the Navy. One promising avenue for reducing these costs is to produce drag-reducing patterns in the protective coatings already employed on marine vessels. Such patterns can be complexreproductions of the exterior of sharks and other aquatic animals or simple rows and furrows. It is also known that patterns that produce super-hydrophobic films also can reduce drag, with a bonus that such films also ameliorate biofouling. In this proposal, we seek to test the ability of photothermal heating to directly write these patterns in the thermally cured thermosets typically employed for Naval coatings.
