ABSTRACT: The fight against dirt settling on the hulls
of ships and more generally on all underwater structures is more than 2000
years. The need for effective antifouling paints, which prevents the establishment and growth of marine
organisms on submerged structures, is universally recognized. In this work, we
synthesize two perfluorinated surfactants from simple monomers. After describing
the reactions, we discuss the different analyzes of the proton nuclear magnetic resonance (1H
NMR), the fluorine nuclear magnetic resonance (NMR I9F), gel
permeation chromatography (GPC) and the light scattering (LS) at a fixed angle
90. The glass transition temperature of the two surfactants
diethylallylphosphonate and allylamine are obtained by Differential Scanning
Calorimetry (DSC). Antifouling paint properties were followed by exposure of
the plates to the marine environment by visual observation.
