A novel method to protect bronze in atmospheric environment: the click-assembly of triazole film Available to Purchase

The authors have prepared the triazole film on copper surface by click reaction and explored its inhibition mechanism.

The protective film is assembled by immersing bronze in solution containing p-toluenesulfonyl azide (TA) and propiolic acid (PA).

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.

This is beneficial to develop the corrosion inhibitors for the corroded copper alloys.
