Study of the Inhibition Mechanism of Imidazoline Derivative Inhibitor on CO2 corrosion for Q235 Steel WANG Bin a DU Min b* ZHANG Jing c Key laboratory of marine chemistry theory and technology, ministry of education, ocean university of china, qingdao 266100, china awb7411@163.com, bsdm06@126.com, cdmh217@ouc.edu.cn Keywords: CO2 corrosion; Imidazoline derivative; Polarization curves; EIS; Quantum chemistry Abstract: Imidazoline derivative inhibitors are successfully used in oil-gas field for CO2 and H2S corrosion.
Several quantum-chemistry studies have been performed in order to supplement the electrochemical results. 2 Experimental 2.1 Materials The test material selected for study was Q235 steel, its composition in wt %C, 0.18; Si, 0.02; Mn, 0.45; S, 0.02; P, 0.01; Fe, balance.
Molecular structure of the imidazoline derivative (1-(2-thioureidoethyl)-2-alkyl imidazoline) was shown as follow: C C � C � CH2 R CH2 �H C �H2 S H2H2 2.2 Electrochemical measurement For electrochemical measurement, the cell assembly consisted of Q235 steel as working electrode, a platinum foil as counter electrode and a saturated calomel electrode (SCE) as a reference electrode with a Luggin capillary bridge.
The data obtained from EIS are in good harmony with that obtained from potentiodynamic polarization. 3.3 Quantum chemistry calculations Fig.4 gives the optimized geometry of the inhibitor molecule and the calculated quantum chemical parameters are shown in Table 3.

The periodic structures were formed with the laser fluence 4.70 mJ/cm 2.
Various types of plasmas (O2, CO2, He-O2 mixtures, Ar) can significantly influence surface chemistry and polymer topology, in case of PET [3-8], PE [9,10], PP [9,11,12] or PTFE [9].
Height and width of prepared structures is shown on Fig.3.
The formation of prepared structures was angle dependent.
