Marine Anti-Fouling Coating
report_problem Problem Statement
Marine biofouling costs the shipping industry $30-60B annually in fuel penalties and maintenance. Tributyltin (TBT) was banned by the IMO in 2008 due to severe ecotoxicity, but replacement copper-based anti-fouling paints still leach heavy metals into marine ecosystems, with copper concentrations exceeding water quality criteria in many harbors. A bio-based anti-fouling coating using naturally-derived compounds could prevent organism attachment through surface energy modification rather than biocide leaching.

flag Success Criteria
Achieve ≥60% reduction in fouling coverage vs. uncoated control at 6 months, no acute toxicity to Artemia at 10x expected leachate concentration per ISO 14669, and coating integrity maintained for full deployment period without delamination
precision_manufacturing Equipment Needed
Marine test site with panel deployment racks, fiberglass and steel test panels, coating application equipment (drawdown bar or spray), digital camera for fouling documentation, image analysis software, analytical balance for erosion measurement, Artemia salina hatch kit, stereomicroscope, chitosan or alginate, copper anti-fouling paint for control
