▎ 摘  要

Perfluorinated polysiloxane [-(SiR1R2-O)n-, where R-1 is -OH and R-2 is -CH2)(2)-(CF2)(5)-CF3],was synthesized from 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFOTES) and hybridized with graphene oxide (GO). The composite (PPFS/GO) was applied to AZ31 Mg alloy for corrosion protection in NaCl. Efficient inhibition by PPFS/GO was realized due to a synergistic effect via the remnant hydrophobic-properties of PFOTES and the high surface area of GO. The polymeric nature of PPFS also contributed to the strong adhesion between the coating layer and AZ31, making this work different to most previous reports where the Mg surface was pretreated before coating.
