Abstract:

A method for preventing accumulation of organisms on a surface exposed to a marine environment. Nano-particles are provided in a water soluble polymer. The nano-particles have a thickness of about 2 nanometers and a major surface area of about 3 microns and are treated by a quaternary ammonium salt. The treated nano-particles are mixed into the water soluble polymer material. This mixture can be applied to the exposed surface. Biofouling is prevented by the sharpness of the nano-particles, sloughing of the water soluble material, and biocidal action caused by the quaternary ammonium salt.
