摘要：

The inhibiting performance of beta-Cyclodetrin-modified acrylamide polymer (poly(AM-co-A-beta-CD-co-NaAA)) on X70 steel in 0.5 M H2SO4 solution has been investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The polarization curves results reveal that polymer acts as a mixed-type inhibitor. The inhibition efficiency is found to increase by increasing the polymer concentration up to maximum 84.9% for 150 mg L-1 at 303 K. The adsorption is confirmed to obey the Langmuir isotherm. The SEM and EDS results demonstrate that X70 surface is protected by beta-Cyclodextrin-modified acrylamide polymer. (C) 2014 Elsevier Ltd. All rights reserved.
