Transparent, biocide-based antifouling coatings for solar cells and sensors (TBAC): Part II, Lifetime extension and technology demonstration

Abstract

This project aims at optimizing formulations and demonstrating high level performance of transparent, antifouling coatings for use on solar cells and sensors on underwater drones or unmanned underwater vehicles. Our prototype formulations, which were developed inan earlier ONR-funded project, are based on existing self-polishing antifouling coating technology, in combination with new specialized raw materials and formulation principles. When tested and evaluated by ONR and The Florida Institute of Technology, we saw 12 weeks of excellent biofouling resistance and maintenance of power generation for a solar cell coating without intermittent cleaning. Similarly, for a more advanced sensor-type coating, we experienced 6 weeks of optically clear performance in Danish seawaters. In the present project, we propose to continue our research on the two novel coatings and bring them closer to actual applications. This involves a demonstration effort in collaboration with the ONR Tech Candidate Program and Florida Institute of Technology, as well as an attempt, formulation-wise, to prolong the lifetime of the optically clear coating to 12 (or more) weeks. In particular, to reach our targets, we will work with a range of modified binders and coating treatments. If successful, the new coatings can fulfill the need of the Navy to secure unproblematic charging of batteries of underwater vehicles or static equipment, as well as allowing underwater sensors prolonged operation.
