RICORR - CORROSION INDICATOR COATINGS
The project will develop a coating that visually indicates when the corrosion process begins in the coated metals. To do this, microcapsules or mesoporous silica particles with colorants inside will be synthesized and incorporated into the coating. The microcapsules will release the colorant when there is an increase in pH in the coating, indicating that the corrosion process is beginning. In the case of mesoporous silica, there will be a change in the color of the silica particles. In the corrosion process, anodic and cathodic zones are generated in the metal. In the anodic zones the oxidation of the metal takes place, while in the cathodic zones the reduction of the medium occurs, which is normally the reduction of O2 to produce OH- ions. Therefore in the cathodic zones an increase in pH takes place. This increase in pH will cause the decomposition of the microcapsules and the release of the colorant or the change of color of the mesoporous silica with the colorant inside. The colorant used preferentially will be phenolphthalein, which shows a color change from transparent to fuchsia in a pH range between 8.3 and 10.
As the main result of this project, it is expected to obtain coatings indicating corrosion on different metals. The objective of the project is to develop coatings that indicate the beginning of the process of the metals they coat.
