Fig. Schematic illustration (cross section view) of the behaviour of a biocide-based antifouling system exposed to sea water. In the TBT-SPCs, the main biocide complementing Cu+ was chemically anchored to the polymer binder matrix while in the tin-free alternatives they are usually embedded in the vehicle.
Fig. Scheme of the TBT-SPC mathematical model. The main processes involved in the activity of a TBT-SPC paint and their interactions are combined with chemical speciation calculations and transport phenomena. The mathematical model can provide reliable estimations of the A/F paint performance.
Fig. SEM picture of a cross section of an exposed antifouling paint based on ZnR and CuO (upper left picture) and its corresponding EDX analysis showing the Cu signals as dots (upper right picture). The intensity of the Zn (not shown) and Cu signal is processed by means of ImagePro, showing a distinct gradient from the unreacted paint to the paint surface (bottom). Under the inert paint, the Zn profile is constant and taken as reference (unreacted Zn-line). The Zn profile in the leached layer (Zn-line) shows a relative residual Zn value at the paint surface of around % of that in the unreacted paint film. The Cu profile (Cu-line) shows approximately the extent of the leached layer. The reason for the larger fluctuations in the Zn signal is a much lower concentration compared to Cu.
