Efficiency of corrosion inhibitors in aqueous solutions depends on several interfacial parameters, which may vary over time. Therefore, reliable electrochemical techniques are demanded for screening the efficiency of corrosion inhibitors and monitoring their performance over time. Here, we evaluate corrosion inhibition efficiency of imidazole-based compounds on bare Cu surfaces and highlight the importance of electrochemical evaluation of the inhibitor over time, characterized by linear polarization resistance techniques as a reliable, instantaneous and non-invasive method for assessing intrinsic inhibitor performance in lab screening studies.

关于时间分辨电化学评估在腐蚀抑制剂筛选研究中的重要性

缓蚀剂在水溶液中的效率取决于几个界面参数，这些参数可能会随时间变化。因此，需要可靠的电化学技术来筛选缓蚀剂的效率并随时间监测其性能。在这里，我们评估了咪唑基化合物在裸露的铜表面上的腐蚀抑制效率，并强调了随着时间进行电化学评估的重要性，其特点是线性极化电阻技术可作为一种可靠，即时且无创的方法来评估内在抑制剂的性能在实验室筛选研究中。
