Unravelling the corrosion protection mechanism of silyl ester by combined electrochemistry and x-ray computed tomography

Recently, encapsulated silyl esters have been shown to act as efficient healing agents for self-healing anticorrosive coatings. While the positive protective effects were irrefutable, the actual protection mechanism has not been clarified yet. In this study, x-ray computed ?-tomography and electrochemical impedance spectroscopy have been...

Model based design of self-healing expandable coatings under different environmental conditions

A long-lasting barrier protection at damaged sites of coated system can be achieved by means of an active response of the primer. This may be attained through the release of reactive liquids from dispersed containers, the increase of the local mobility of the polymeric network, or the expansion of (dispersed elements in) the primer [1]. Such...
