Abstract Graphene derivatives have received significant attention as excellent anti-corrosion coating materials, but their application as corrosion inhibitors in the aqueous medium is restricted due to poor solubility. Chemical functionalization is one of the essential methods to improve solubility and corrosion inhibition performance. In present work, two novel surfactant modified graphene oxide (GO) derivatives were designed, and their corrosion inhibition performance on mild steel corrosion was assessed for the first time in standard 1 M HCl with electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) methods. The results of electrochemical studies indicated that both the inhibitors retard corrosion by adsorption mechanism. The PDP studies showed that both the inhibitors are mixed type. The adsorption of these compounds on the metal surface was confirmed by scanning electron microscopy (SEM) and atomic force Mmicroscopy (AFM) methods.

表面活性剂改性氧化石墨烯作为酸性介质中低碳钢的新型缓蚀剂

摘要 石墨烯衍生物作为优良的防腐涂层材料受到了广泛的关注，但由于溶解性差，限制了其在水性介质中作为缓蚀剂的应用。化学功能化是提高溶解性和缓蚀性能的重要方法之一。在目前的工作中，设计了两种新型表面活性剂改性氧化石墨烯 (GO) 衍生物，并首次通过电化学阻抗谱 (EIS) 和动电位极化 (PDP) 在标准 1 M HCl 中评估了它们对低碳钢腐蚀的缓蚀性能方法。电化学研究结果表明，两种抑制剂均通过吸附机制延缓腐蚀。PDP 研究表明两种抑制剂都是混合型的。
