Abstract Abstract：The polythiophene (PTh) film on stainless steel sheet (SS) was synthesized by potentiostatic method in pure boron trifluoride diethyl etherate (BFEE) solution. The structure, morphology and thermostability of the PTh film were studied by Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The corrosion performance of the polymer film was investigated in 3.5% (mass) NaCl solution, by using anodic polarization and electrochemical impedance spectroscopy (EIS). The results showed that the as-electro synthesized PTh film was uniform and shiny, had a good thermostability. Ecorr of the PTh coated SS shifted towards more positive side than bare SS about 220 mV and Jcorr decreased two orders of magnitude, indicating that the PTh film has excellent corrosion resistance.
