preparation of self-healing and anticorrosive epoxy coatings loaded with various inhibitor doped pani nanofibers

Herein, polyaniline (pani) nanofibers, as an efficient and smart anticorrosive material were synthesized and used within epoxy matrix. to evaluate and compare the role of the doping agents on the corrosion resistance of the employed nanofibers, phytic acid and tannic acid were used as disparate doping agents. the prepared nanofibers were characterized thoroughly and their ability for improving the corrosion performance of the prepared coating was evaluate by electrochemical impedance spectroscopy (eis). the results of the polarization and eis tests showed that the anticorrosion properties of tannic acid doped pani (ta-pani) were significantly better compared to phytic acid doped pani (pa-pani) nanofibers.
