Étude par coulométrie de la pénétration de l'eau dans des films de polymères formulés

Abstract: IntroductionL'eau diffusant dans une peinture provoque son gonflement [1] et peut entraîner une perte d'adhésion, une détérioration des propriétés mécaniques ou un début de corrosion [2] du support. Mais, dans le cas des peintures antisalissures, elle est essentielle en regard de la protection recherchée par solubilisation et libération de molécules bioactives. Le phéno-mène de pénétration d'eau dans les films de peintures antisalissures reste encore peu étudié bien qu'il soit au centre de l'hydrolyse, de l'ér… Show more

“…However, such an assumption was not regarded as valid for the modeling of the copper leaching from insoluble matrix paints37, 39, 40 and saturation at the pigment front was assumed instead. For the paints studied here, the assumption of Cu(I) saturation at the pigment front is supported by the relatively significant water penetration characteristic of rosin‐based products,41, 42 potentially leading to long contact times between Cu 2 O particles and seawater prior to exposure at the pigment front. Furthermore, and in good agreement with the latter discussion, the use of relatively hydrophilic plasticizers (such as Plasticizer 233) has been shown to boost the copper leaching process 43…”

“…4 In the present study, the hydration characteristics of five polymers are analyzed. These polymers (Figure 1) were chosen in reference to previous works on their hydrolytic degradation and global hydration: 5,6 •An organotin copolymer (POS) which associates methyl methacrylate and tributyltin methacrylate monomeric units.…”
