The objective is to create sensors that can efficiently detect corrosion at early stages. Moreover, we want to develop sensors that can monitor the efficiency of coatings for anticorrosion. In a first approach, we will focus our research on sensors for the detection or corrosion of steel. The nanosensors will be embedded in coatings on the top on metal substrates. Nanocontainers are particularly useful for that purpose because the thickness of the protective coating usually in the range of several microns. Furthermore, the feedback is also faster because of the very high surface area offered by sensors at the nanoscale. The nanocontainers shell avoids interactions between the dye and coatings precursors such as hardeners, which can yields to premature activation of the dye. Due to the limitation of molecular sensors explained in the literature review above, we want to develop nanosensors that will limit the leaching of the sensors in the environment.
