The objective of this project is to mature and demonstrate durable, economical, and nontoxic coatings that will prevent fouling organisms from growing on MHK structures. A novel foul-release coating recently developed (initial patents filed in 2016 and 2017) at PNNL, Superhydrophobic Lubricant Infused Composite (SLIC) technology, will be adapted to provide the durability necessary for >5 year protection in the marine environment.
