| Abstract: | Resistance to corrosion of the nano-composite silicone coatings and the diffusing behavior of corrosion media through the different silicone coatings were researched by electrochemical impedance spectroscopy(EIS) techniques.The results showed that the protective property of silicone coating with nano-SiO2 composite was much better than that of silicone coating with conventional SiO2 and that of silicone varnish coating.Nano-SiO2 had more surface activity,and it could combine more tightly with silicone resin,which could make the coatings more compact.The corrosive media could hardly transport into these compact coatings,so the silicone coatings with nano-SiO2 addition has better anti-corrosive property than that with conventional SiO2 addition. |
