Meanwhile, the coated surface was hydrophobic with a contact angle of 107.2°since the introduction of methyl groups and methylene groups. Static immersing corrosion test, potentiodynamically polarization curve and electrochemical impedance spectroscopy were conducted to evaluate the film corrosion performances. The results of potentiodynamically polarization curve and EIS in 55wt% LiBr solutions at room temperature in atmospherical pressure indicated that the corrosion current density of BMBSE film coated surface was 4 orders of magnitude smaller than that of bare SUS304 steel, and the impedance was increased by a factor of 10000. Static immersing corrosion test presented that the BMBSE film can significantly increase the corrosion resistance in 55wt%LiBr solution at 180°C compared with stainless steels.
