Optical images of both healed and control coatings captured four months post-exposure to a corrosive aqueous salt solution during electrochemical characterization: (a) before exposure, (b) healed, (c) Type A (PDMS), (d) Type B (DBTL), (e) Control (no fibers). Comparing the healed coating before and after corrosion exposure reveals similarity in appearance. Conversely, the control cases comprising type A (PDMS) fibers only, type B (DBTL catalyst) fibers only, and no fibers (silicone binder only) exhibit unmistakable signs of corrosion damage [89] (Permission to use was granted by Elsevier).
