The corrosion inhibition behaviors for the self-assembled monolayers (SAMs) of ammonium pyrrolidine dithiocarbamate（APDTC） on the copper surface in HCl and NaCl solutions had been investigated by polarization curve, respectively. Prone to be adsorbed on the copper surface, the APDTC SAMs restrain both anodic oxidation and cathodic reduction process. The results indicated that APDTC SAMs had good corrosion inhibition effects on copper in both HCl and NaCl solutions.

ABSTRACTThis work investigates the effects of concentration of organothiol molecules and temperature used during self-assembled monolayers (SAMs) formation on quality of the organothiol SAMs coating layer obtained in terms of wettability, corrosion inhibition efficiency and carbon to copper ratio. The organothiol SAMs were coated on copper substrates prepared by electro-polishing followed by oxygen plasma treatment for 15 s. Three types of organothiol SAMs including 1-octanethiol (OTT), 2-ethylhexanethiol (2-EHT) and 2-phenylethanethiol (2-PET) were investigated. Concentration of organothiol molecules ranging from 0.005 to 0.02 M in isopropanol and forming temperature ranging from -15 to 50°C were studied. It was found that all organothiol SAMs of 0.01 M provided the SAMs coating layer with the highest quality. The SAMs formed at 40°C with OTT and 2-EHT, and at 0°C with 2-PET were the most favorable condition with the highest water contact angle of 124.79o, 130.66o and 120.58o at corrosion inhibition efficiencies of 96.24%, 99.37% and 98.90%, respectively.

The Self-assembled monolayers (SAMs) of Schiff base had been formed on oxidized surfaces of copper. Schiff base used in this paper is N-2-hydroxyphenyl- (3-methoxy-salicylidenimine), designated V-bso. X-ray photoelectron spectroscopy (XPS), polarization curves, electrochemistry impedance spectroscopy (EIS) and the interface capacitance measurements have been employed to investigate the structure, formation and composition of these monolayers. XPS analysis show that the valence of the copper in the surface films is +2. The polarization curves and the EIS results indicate that the films of CuO, V-bso, and V-bso modified oxidized copper all have good corrosion inhibition efficiency. The IE of the V-bso modified oxidized copper is higher than that of the V-bso modified copper and the oxidized copper layer, just because the former has two layers. The results of the interface capacitance show that the self-assemble films of the V-bso on the oxidized copper surface have good potential stability.

Group Form

The newly synthesized 1,4-naphthoquinones linked via nitrogen atom to a short chain with terminal sulfanyl group form self-assembled monolayers on gold. The main electrochemical parameters of the monolayers were determined by cyclic voltammetry. Combined voltammetric and in situ Fourier-transform surface-enhanced Raman spectroscopic studies of the Au electrode modified with the title compounds clearly evidence that naphthoquinone group transforms into naphthalenediol during a reduction process.
