A novel double-hydrophilic copolymer (acrylic acid-isoprenyl polyethoxy carboxylate, AA-TPEL) is synthesized and the structural properties are identified by FT-IR, 1HNMR and GPC analyses. The inhibitory behavior of the copolymer is determined by using a static scale inhibition method. It is shown that AA-TPEL exhibits an excellent ability to control the formation of CaCO3 scale with an inhibition efficiency of 88.67 % at the 8 mg L–1, and it still maintains a superior efficiency even at increasing solution temperature, pH, and Ca2+ concentration. Weight loss test, potentiodynamic polarization and electrochemical impedance spectroscopy are applied to investigate the inhibition efficiency on mild steel corrosion. All measurements show that, AA-TPEL acts as an efficient corrosion inhibitor and also displays a superior ability to prevent the corrosion of mild steel with approximately 83.21 % inhibition efficiency at the low level of 10 mg L–1. Scanning electron microscopy (SEM) and X-ray powder diffraction (XRD) are used to characterize the surface morphology of CaCO3 and steel.


Ein neues doppelt-hydrophiles Copolymer (Acrylsäure-Isoprenylpolyethoxycarboxylat, AA-TPEL) wurde synthetisiert und die strukturellen Eigenschaften werden durch FT-IR-, 1HNMR- und GPC-Analysen identifiziert. Das Inhibiervermögen des Copolymers wurde mit der Methode der statischen Kesselsteinbildung bestimmt. Es wurde gezeigt, dass AA-TPEL die CaCO3-Kesselsteinbildung mit einer 88,67 %-igen Inhibitionseffizienz bei 8 mg L–1 kontrolliert und dass das Copolymer trotz ansteigender Lösungstemperatur, zunehmendem pH-Wert und Ca2+-Konzentration weiterhin einen überlegenen Wirkungsgrad hat. Der Gewichtsverlusttest, die potentiodynamische Polarisation und die elektrochemische Impedanzspektroskopie wurden eingesetzt, um die hemmenden Eigenschaften bei der Korrosion von Weichstahl zu untersuchen. Alle Messungen zeigten, dass AA-TPEL als effizienter Korrosionsinhibitor wirkt und auch bei niedrigem Gehalt von 10 mgL–1 die Korrosion von Weichstahl mit einer etwa 83,21 % Inhibitionseffizienz verhindert. Rasterelektronenmikroskopie (SEM) und Röntgenpulverdiffraktion (XRD) wurden zur Charakterisierung der Oberflächenmorphologie von CaCO3 und Stahl verwendet.
