Study on preparation of amphiphilic silane and its modification on copper surface

Abstract

Abstract The amphiphilic polymers monosilane and disilane were synthesized in this sdudy. The pretreated copper plates were modified by the synthesized silane. The copper plates after silane treatment were characterized by measuring total reflection fourier infrared spectroscopy (ATR-FTIR), electrochemical impedance, X-ray photoelectron spectroscopy, and contact angle. ATR-FTIR and XPS confirmed that the amphiphilic polymer silane was successfully grafted onto copper surfaces; the contact angle measurement results showed that the contact angle of the surface of the copper plate after grafting the silane was reduced from 83°to 50°; the electrochemical impedance results showed that the electrochemical transfer resistance on the surface of the copper plates after grafting the silane was increased from 702.8 to 6452.. This study has important reference significance for inhibiting the corrosion of copper plates.
