Resumen:

Eco-friendly coatings are a step forward to protect the environment and recycled expired medicines and waste mesoporous particles used as containers combined with waterborne organic coating schemes, seem a good idea to protect the environment. This chapter outlines such schemes, giving examples of them. Discarded fluconazole and lansoprazol medicines are used to obtain the inhibitors, combining with waste silica or kaolinite particles as containers being part of a waterborne alkyd organic coating. The hybrid coating system efficiency is evaluated for steel corrosion, in simulated corrosive environment, using electrochemical impedance and polarization techniques. Good corrosion protection performance is obtained for the coating system for extended periods of immersion. The results demonstrate the good barrier properties of the hybrid coatings, showing the particles task to store and liberate the corrosion inhibitor, when it is needed. © 2016 by Scrivener Publishing LLC.
