摘　　要：New stared compounds including norfloxacin fragments were prepared via a multi-step route,which were employed as the target corrosion inhibitors(TCIs)for mild steel in 1 mol/L HCl solution.For comparisons,the linear compounds including a single norfloxacin part employed as the reference corrosion inhibitors(RCIs)were synthesized.The molecular structures of the stared compounds were confirmed.The material simulation calculations suggest the presence of large binding energies of the stared compounds on mild steel surface.The enhanced chemisorption of the stared compounds on mild steel surface was demonstrated,which could be resulted by the chemical complexion of the target stared molecules with iron atoms.The reinforced adsorption of the target compounds on mild steel surface was investigated by atomic force microscopy(AFM)and scanning electron microscopy(SEM).The electrochemical analyses reveal the super protection of the TCIs for mild steel in HCl solution,and the anticorrosion efficiency reaches 96.45%(TCI1,0.050 mM)and 96.61%(TCI2,0.010 mM)at 298 K.
