Self-assembled tetraaniline nanofiber as a novel anticorrosive pigment for waterborne epoxy coatings

Researchers from China synthesized the self-assembled tetraaniline nanofiber in 1 M HCl solution and investigated the the addition of tetraaniline based conducting nanofiber (TANF) on the anticorrosive properties of waterborne epoxy coatings on Q235 mild steel. ıt was found out that the self-assembled TANF possesses excellent solubility, tiny nanofibrous structure and reversible redox behavior. The anticorrosion performance of epoxy coating with and without self-assembled tetraaniline nanofiber was investigated by electrochemical impedance spectroscopic (EIS), polarizing curves and scanning vibrating electrode technique (SVET).

The incorporation of 0.5 wt% the self-assembled tetraaniline nanofiber into epoxy coating improved corrosion resistance properties compared to pure waterborne epoxy coating. Moreover, it was revealed by  X-ray diffraction (XRD) that the addition of electroactive the self-assembled tetraaniline nanofiber could facilitate to form a passive metal oxide layer beneath the coating as proved by characterization of rust layers.
