Abstract (en)
A long-lasting, practical, effective and economic method of rendering a surface antifouling properties is achieved by attaching very thin copper-containing sheets directly to said surface. It was found, surprisingly and contrary to common belief, that such very thin sheets, because of their low weight, flexibility and feeble thickness, could be made to follow any shape so closely, that many commercially available water-resistant adhesives are sufficient to exclude water from penetrating in-between the surface and the copper containing sheet so that said sheets are basically held in place by the hydraulic pressure exerted on the sheet, once the structure is submerged. The new method avoids all the disadvantages of the more common use of toxic paints, as the surface will have a lower degree of roughness, be smear-free, offers long-term protection, much reduces the environmental hazards and further protects the surface from other effects of its contact with water.
