New bionic ship coatings should be developed on the basis of permanently maintaining the surface of underwater air

One research project involved marine coatings that allowed air layers to remain underwater. In addition, this reduces frictional resistance.
, corrosion and biodeface are the three key issues of shipping

The research project Air Hold Surface (ARES) - a collaboration between the Karlsruhe Institute of Technology (KIT) and the Universities of Bonn and Rostock - is working on new coatings for ships that permanently retain air layers underwater, significantly reducing frictional resistance to the surface. At the same time, they prevent the release of toxic substances and biological contamination and corrosion in marine coatings by preventing contact between ships and water.
new bionic ship coatings
are based on a permanent underwater gas-protected surface ("air coating technology"), a new bionic ship coating will be developed, in which the ship is lubricated underwater with lubricated air. New environmental technologies offer great potential for reducing friction while providing a basis for environmentally friendly "anti-fouling" that does not release toxic materials into the ocean and provides corrosion protection. So far, anti-fouling has treated hulls with paint containing heavy metals to prevent the growth of algae and mussels.
