| 英文摘要 | N-alkylation of sulfosalicylic acid-doped polyaniline (PANI-SSA) was used to promote the anticorrosion performance of PANI-SSA/epoxy coating for 5083 Al alloy. PANI-SSA was modified with C5H11Br and C12H25Br in polar solvents IPA (isopropanol) and DMF (dimethylformamide), and then characterized by FTIR, XPS and sedimentation experiments. Results showed that alkanes were successfully linked onto the PANI-SSA chains. The compatibility between N-alkylated PANI-SSA and epoxy/xylene solution was improved. SEM results proved a better dispersion performance of N-alkylated PANI-SSA in epoxy coatings, with less holes and aggregations. Corrosion protection of the epoxy coatings incorporating PANI-SSA and N-alkylated PANI-SSA on 5083 Al alloy was studied by EIS and adhesion measurements in 3.5% NaCl solution. It turned out that the epoxy coating including C12H25Br-modified PANI-SSA in DMF has yielded the highest values of impedance modulus and best protective properties.
