چکیده
Elect rochem ical synthes is of poly 3-amino-5-hydrox yp yrazole (PAHP) on copp er elec trode sur-face was carried out by cyclic voltamm etry techni que in 0.03 M 3-amino- 5-hydrox ypyrazol e solut ion containing 0.3 M oxalic acid. The formati on of dark brown PAH P on co pper surfa ce was charac terized by cycl ic volt am-metry, FTIR an d scanni ng electron microsc opy tech-niques. The corros ion charac terist ics of copp er/PAH P electrode wer e evalua ted by elec trochemi cal met hods and elec troche mical imped ance spectroscopy in 3.5% NaCl solution. The obtain ed results indicate d that PAH P thin film coating was an excellent inhi bitor and control led copper corros ion agains t corros ive agents in 3.5% NaCl solution.
