Developing efficient inhibitors based on eco-friendly compounds for steel protection is crucially important. Here the synthesis and characterization of a new hybrid inhibitor based on intercalation of 6-aminohexanoic acid (6-AHA) in layered aluminum tri-polyphosphate (ATP) are reported. ATP and the inorganic-organic hybrid inhibitor system ATP-6-AHA are characterized by XRD, thermal gravimetric analysis (TGA), SEM, IR and Raman spectroscopy. The interlayer space of ATP is expanded by 10.1 Å, with 6-AHA planes arranged in bilayers. Corrosion efficiency of ATP-6-AHA was evaluated in 0.1 M and 3.5 % NaCl using electrochemical impedance spectroscopy (EIS) and showed a significantly reduced corrosion for steel S235.

开发基于环保化合物的高效缓蚀剂对钢的保护至关重要。在此报道了基于6-氨基己酸（6-AHA）在层状三聚磷酸铝（ATP）中的嵌入的新型杂化抑制剂的合成和表征。通过XRD，热重分析（TGA），SEM，IR和拉曼光谱对ATP和无机-有机杂化抑制剂体系ATP-6-AHA进行表征。ATP的层间空间扩展了10.1Å，双层中排列了6-AHA平面。使用电化学阻抗谱（EIS）在0.1 M和3.5％NaCl中评估了ATP-6-AHA的腐蚀效率，结果表明S235钢的腐蚀显着降低。
