Preparation and Corrosion Inhibition of GPTMS/PFDS Self-assembled Bilayer on 430 Stainless Steel

Self-assembled bilayer of GPTMS/PFDS was prepared on the surface of 430 stainless steel. Fourier transform infrared (FTIR) spectroscopy, electrochemical measurements, contact angle and scanning electron microscopy (SEM) were used to study the adsorption of self-assembled films and their corrosion inhibition for 430 stainless steel. The results showed that the GPTMS/PFDS bilayer exhibited better corrosion resistance than the single layer film of GPTMS SAM or PFDS SAM.
