Superhydrophobic coatings have important applications in maritime industry. They can yield skin friction drag reduction for ship hulls, thus increasing fuel efficiency. Such a coating would allow ships to increase their speed or range while reducing fuel costs. They can also reduce corrosion and prevent marine organisms from growing on a ship's ...
Although chemical fouling inhibitors, metallic coatings, and cleaning processes can be used to reduce fouling, non-toxic surfaces with anti-fouling properties are ideal for fouling prevention. To be considered effective, an ultra-low fouling surface must be able to repel and withstand the accumulation of detrimental aggregates down to less than ...
New ship being prepared for launch, showing fresh anti-fouling paint Ship hull being cleaned of fouling in drydock. Anti-fouling paint is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth of and facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability.
Making a surface superhydrophobic represents an efficient means of imparting antimicrobial activity. A passive antibacterial effect results from the poor ability of microbes to adhere to the surface. The area of superhydrophobic textiles takes advantage of this and could have potential applications as antimicrobial coatings.
The high stability is a consequence of a seemingly paradoxical combination of a superhydrophobic (extremely water repellent) surface with hydrophilic (water attractive) patches on the tips of the structures. When submerged under water, no water can penetrate the room between the hairs due to the hydrophobic character of the surfaces.
Pettit Marine Paint is a manufacturer of marine (boat) coatings, antifouling boat bottom paint, varnish and epoxies for consumer and commercial markets. The company was established in 1861, its headquarters are located in Rockaway , New Jersey .
