FLUORINATED POLYMERS FOR CORROSION PROTECTION OF METAL
The hydrophobic and corrosion resistive film of cross-linked poly(hexafluoroisopropyl methacrylate) was prepared by photopolymerization. The starting materials were a monomer of 1,1,1,3,3,3-hexafluoroisopropyl methacrylate, a photoinitiator of hydroxycyclohexyl phenyl ketone, and a cross-linker of poly(ethyleneglycol diacrylate). Photopolymerization was used to start polymerization and to cure the polymer film on an aluminum surface. Drop-casting was used to deposit the fluoropolymer onto an aluminum substrate (AA 3003). The fluoropolymer film has high corrosion protection when measured by potentiodynamic polarization and open circuit potential techniques in an aqueous solution of 3.5% NaCl. Fourier-transform infrared spectroscopy was used to monitor the polymerization process. The dynamic contact angle technique was used to measure the hydrophobicity for the fluorinated polymer coating. Thermal stability of the fluorinated polymer was measured using thermogravimetric analysis. Treatment with strong acid followed by contact angle measurements before and after the treatment confirmed the chemical resistance for the coated aluminum.
