摘要

The present work aims to prepare new ionic liquid polymers based on protonation of diethylethanolamine (DEEA) with polymerizable monomers such as 2-acrylamido-2-methyl propane sulfonic acid(AMPS) and acrylic acid (AA). The polymerizable monomer was polymerized without solvent toprepare viscous poly ionic liquid as AMPS/AA-QA. The chemical structure and thermal characteristicsof AMPS/AA-QA were investigated by NMR, DSC and TGA. The wetting characteristics ofAMPS/AA-QA were measured at the steel surface by measuring the contact angles. This workdescribes the successful performance of AMPS/AA-QA as eco-friendly corrosion inhibitors for steel inacidic chloride solution. Corrosion inhibition of steel was carried out by electrochemical techniques.The experimental results reveal that AMPS/AA-QA is efficient mixed type corrosion inhibitors.Inhibition efficiency of 93.7% is reached with 25ppm of AMPS/AA-QA. The Nyquist plots composedof one capacitive loop and its diameter increases with increasing AMPS/AA-QA concentrations. Theadsorption of AMPS/AA-QA on steel surface obeys Langmuir isotherm.
