School of Chemistry and Chemical Engineering, Harbin Institute of Technology, Harbin 150001, China; 2. Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining 810008, China Received 25 October 2015; accepted 10 May 2016 Abstract: A multifunctional polymeric nanofilm of triazinedithiolsilane monosodium salt, which can resist corrosion and activate copper surface concurrently, was prepared by galvanostatic technique and the following hydrolysis−condensation approach. Electrochemical tests were carried out to evaluate the resistant ability of nanofilm. The changes of functional groups atop the nanofilms were monitored with Fourier transform infrared spectroscopy (FT-IR) and contact angles (CA) simultaneously. The chemical composition and the morphology of the polymeric nanofilm were investigated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM), respectively. The results reveal that the preferentially developed disulfide units protect the copper during the whole preparation process, and the subsequently hydrolyzed nanofilms without/with heating shape into new interface phases bearing the multifunctionality. This multifunctional interface (the polymeric nanofilm on copper s
