Report of Progress on Antifouling Coatings
Abstract
During the early part of 1930, the question of protective coatings was discussed at this laboratory. In the literature and in practice, the production of antifouling surfaces for ships had all been based on attempts at poisoning the fouling organisms. In general, the effectiveness of poisons depends on the toxicity, their concentration, this on their solubility. Thus, the more soluble the poison in the paint film, the more effective it will be to prevent fouling, and the shorter the time it will be effective, since the supply of un-saturated solvent, sea water, is to all intents and purposes infinite. It seemed to the laboratory that a fresh method of approach to the problem was to try to produce surfaces such that there would be a force in a direction away from the surface, either a surface tension or small electrical force, so that the minute organisms could not approach closely enough to adhere.
