Preparation of Perfluorinated Surfactant Activates for Antifouling Paints

Abstract

Antifouling paints are the most reliable way to prevent biofouling of submerged surfaces. The high toxicity of organotin paints, prompted us to look for ideas to develop paints that do not present environmental risks. In this work, we prepare a painting by a modification of acrylic acid monomer containing a free carboxyl group. The biocide that is selected is the perfluorinated chain with eight carbons. Chemical modifications of the resins are made through a radical reaction. The magnitudes of changes are monitored by proton nuclear magnetic resonance NMR, gel permeation chromatography (GPC) and the light scattering (LS) at a fixed angle 90¡æ. The glass transition temperature of the surfactant is obtained by the differential scanning calorimetry (DSC). The antifouling properties of the paint are followed by exposure of panels to the marine environment by visual observation.
