摘要：
In order to investigate the effects of waterborne polyaniline/versatate-fluoro-acrylate (PANI/VFAc) composite coating on anticorrosion performance of Q235 steel, VFAc emulsion was synthesized firstly by using versatate (Veova 10) and dodecafluoroheptyl methacrylate (DFMA) as the functional monomers, and after mixed with PANI emulsion, it was applied to the surface of Q235 steel to prepare PANI/VFAc composite coatings. Then, the structure of VFAc was characterized by TEM and FTIR, the surface performance of composite coatings was evaluated by XPS and contact angle (CA), and the influences of different modified acrylate emulsions on the anticorrosion performances of the composite coatings were investigated by electrochemical method. The results show that the water contact angle of PANI/VFAc composite coating is 97.56°, the grade of wet adhesion is 0, which means the coating shows preferable hydrophobicity. The corrosion current density is 8.72×10-8 A·cm-2, and the electrochemical impedance reaches 106 Ω·cm2. The conclusions obtained show that PANI/VFAc composite coating has preferable anticorrosion performance for Q235 steel. © 2016, BUAA Culture Media Group Ltd. All right reserved.
