Smart epoxy coating for corrosion protection
During the study, calcium phosphate was encapsulated into mesoporous silica nanoparticles (MSN). The effect of pH on the structure and morphology of the MSN and the release of calcium phosphate from the MSN was investigated. Epoxy coatings with encapsulated (3 wt%) and non-encapsulated (3 wt% and 5 wt%) calcium phosphate were formulated and their anti-corrosive performance was evaluated.
Results showed that encapsulation of the calcium phosphate as inhibitive pigment in the coating can enhance the anti-corrosive performance by preventing spontaneous pigment dissolution and controlling the pigment's release from the coating.
The study has been published in Progress in Organic Coatings, Volume 165, April 2022.
