Flake aluminum powders with excellent corrosive resistance properties are attractive materials in many technol. applications. Here, a convenient strategy is employed to encapsulate the aluminum powders by using silicon-fluoropolymer composite film, by which the chem. resistance of aluminum-based pigments is significantly improved. A basic layer of SiO2 is formed on the surface of the flake aluminum powders via sol-gel process. For the good compatibility between the silicon and fluorine, a uniform and dense layer of poly (trifluoroethyl methacrylate) (PTFEMA) is pasted tightly on the silicon layer initially formed by solution polymerization Protected by this kind of composite silicon-fluoro-layer, the encapsulated aluminum powders were highly stable when they dipped into strongly alk. solution (1.25 M, pH > 14). The morphol. of composite layers on the aluminum powders are characterized by means of SEM. The structures of silicon-fluoropolymer composite film are tested by Fourier transform IR spectroscopy (FTIR), energy dispersive spectroscopy (EDS) and XPS. The relationship between the usage of monomers and crosslinker on corrosion inhibition properties is systematically investigated. The phenomenon of hydrogen gas evolution is eliminated by the PTFEMA/SiO2 hybrid films owing to an efficient fluorinated protective film on aluminum pigments.
