Electrochemical evaluation of the rapid self-healing behavior of poly (borosiloxane) and its use for corrosion protection of metals

Self-healing of soft poly(borosiloxane) via reptile motion within only 30 s at 45 degrees C has been observed both visually and microscopically. A poly(borosiloxane) coating was utilized for corrosion protection of a metal surface (in this case Ti) and its behavior was analyzed by electrochemical impedance spectroscopy. Even in a corrosive solution such as 3% NaCl aqueous solution, the polymer provided a high degree of corrosion protection, demonstrating self-healing of scratches in situ.
