The shipping industry faces numerous operational problems, but perhaps one of the most serious is the fouling of ships' hulls by barnacles, seaweed, or slime-creating bacteria. This fouling also imposes additional costs; for example, the fouling of a ship's hull can, create enough turbulence so as to increase fuel consumption by as much as 30%. Navies and merchant lines across the world, therefore, have been researching solutions to reduce the incidence of fouling.

Most approaches center around painting hulls with paints containing copper or triorganotin (a tin-based compound). However, such paints leach highly toxic compounds into the water, destroying marine life. As a result their use is becoming highly restricted.

Materials scientists at Cornell University, led by Professor Christopher Ober, have produced two varieties (hydrophilic and hydrophobic) of non-toxic paint that prevent marine fouling. The paints impart their...
