A poly-acetamide-acetoxyl methyl-propylsiloxane (PAAMPS) polymer containing a cerium (Ce) oxide derivative was synthesized through three spontaneous reactions: condensation, amidation, and acetoxylation. The PAAMPS synthesizing took place between the Ce acetate dopant and aminopropylsilane triol (APST) as the film-forming precursor aqueous solution at 150[degrees]C. PAAMPS was evaluated for use as a corrosion-preventing coating for air-cooled condensers consisting of two metal components: aluminum fins and carbon steel tube. The key factors to ensuring the maximum performance of the PAAMPS/Ce oxide coating system in mitigating the corrosion of both aluminum and steel ...
