Abstract
Purpose
The authors have prepared the triazole film on copper surface by click reaction and explored its inhibition mechanism.
Design/methodology/approach
The protective film is assembled by immersing bronze in solution containing p-toluenesulfonyl azide (TA) and propiolic acid (PA).
Findings
Fourier transform infrared spectroscopy (FT-IR) indicates that triazole (TTP) film was formed on bronze surface via click chemistry reaction between TA and PA. It shows TTP film has a good protection for bronze in the atmospheric environment simulation solution. Quantum chemical calculation (QC) and molecule dynamics simulation suggests TTP molecule adsorbs on bronze surface via N and O.
Originality/value
This is beneficial to develop the corrosion inhibitors for the corroded copper alloys.
