Click-assembling triazole membrane on copper surface via one-step or two-steps and their corrosion inhibition performance

摘要

Triazole membrane was prepared on copper surface via one-step or two-steps click chemistry reaction of azide and alkyne compounds. Fourier transforms infrared spectroscopy (FT-IR) suggests the formation of triazole membrane on copper surface through both of one-step and two-steps click-assembling. The electrochemical results indicate that the protection efficiency of triazole click-assembling membrane forming via one-step is better than that for two-steps. The surface film on copper via one-step click-assembling is mainly composed of the triazole membrane. As for two-steps click-assembling, the triazole membrane is mainly produced in the defect of the alkyne inhibition film. (C) 2017 Published by Elsevier B.V.
