摘要	The formation of polymer film of propargyl alcohol(PA) and its protective ability against corrosion in Fe/H2SO4 and Fe/H2SO4 + H2S systems have been investigated using impedance measurement. The composition and morphology of the corrosion surface of iron, on which PA polymerized at different times, were obtained with the aid of SEM and AFM as well as EDX. The results showed that PA polymerized into compact polymer film in Fe/H2SO4 and Fe/H2SO4 + H2S systems, which made iron surface smooth and have a morphologies of regular square structure in microscopic level. In Fe/H2SO4 system, macroscopic continuous polymer film of PA was not formed leading to local corrosion on electrode surface. In Fe/H2SO4 + H2S system, the adsorption of H2S and HS- on electrode surface slowed down the formation of polymer film of PA. However, the iron sulfide, produced after a longer time, increased the continuity of the polymer film of PA and therefore, the polymer film could perform its long-term inhibition action.
