Abstract
Series of advanced anticorrosive hybrid coatings comprising of organo‐soluble fluorinated polyimide (SFPI) matrix dispersed with different feeding ratio of inorganic silica (SiO~2~) nanoparticles has been successfully prepared through a conventional chemical imidization of polyimide and acid catalyzed sol–gel process of TEOS. It should be noted that the incorporation of SiO~2~ nanoparticles into the SFPI matrix can effectively enhance the corrosion protection performance on cold‐rolled steel (CRS) electrode against corrosive species in saline condition when compared with that of neat polymeric coatings based on a series of standard electrochemical corrosion measurements, such as corrosion potential, polarization resistance, corrosion current, and impedance spectroscopy.
