“…We believe that, as described by Keller et al, the octadecanethiol reduces the CuO to Cu þ by formation of the dithiol, which results in the deposition of a multilayer of a copper thiolate complex (CuSC 18 H 37 ). [26] Once functionalized, the nanowires are oxidation-resistant under ambient conditions, which is similar to the protection provided by self-assembled monolayers on flat Cu films. [27] Cu/polystyrene nanocomposites were produced by dispersing the nanowires or Cu powder into a solution of polystyrene in CH 2 Cl 2 .…”

Summary: A scalable synthesis of copper nanowires by alternating current electrodeposition into porous aluminium oxide was used to produce multigram quantities of 16 nm diameter by >2 µm long nanowires. Polystyrene nanocomposites were prepared by solution processing. The composites containing unpassivated nanowires were non‐uniformly dispersed and showed electrical percolation at ≈2 vol.‐% Cu loading, while the composites containing HSC18H37‐passivated nanowires were uniformly dispersed, but remained resistive up to at least 10 vol.‐% Cu loading.Copper nanowires prepared by alternating current electrodeposition into porous aluminium oxide templates.magnified imageCopper nanowires prepared by alternating current electrodeposition into porous aluminium oxide templates.

“…Here we mention that silver evaporated on thiolate/Au(l 11) in vacuum has indeed been observed to penetrate the layer [11,82]. Let us also mention that thiolates readily adsorb on Cu(lOO) [83] and that even multilayer copper thiolates can form [84]. All these arguments lead us to propose a CH3(CH2)"_IS/Cu/Au(lll) structure.…”

We have investigated the structure and thermal dynamics of alkanethiolate layers on Au(lll) with variable temperature scanning tunnelling microscopy (STM), X-ray photoelectron spectroscopy (XPS) and voltammetry. The results build the basis for a study of electrodeposition of copper on alkanethiolate-covered Au(lll). Electrodeposition has been studied as a function of the thiolate chain length, the deposition potential and the temperature. Time-resolved [1][2][3][4][5][6][7].

“…The thickness values were calculated using the simple single-film model and fixed values for the optical constants (n = 1.429, k = 0) of the adsorbates which is an average value of many organic compounds. 30 Contact angle measurements were performed in order to obtain information about the properties of the surface of the monolayer as well as the packing density. The water contact angle measurements (CA) on bare cupronickel and treated samples were performed using a goniometer DataPhysics Contact Angle System OCA 20, with a drop of 2 μL deionized water under the ambient atmospheric conditions.…”

Self-assembled mono-and multilayers of stearic acid have been examined as corrosion protection systems for copper-nickel alloy in 3% sodium chloride solution. We found that self-assembled multilayers of stearic acid provide more efficient and durable corrosion protection to copper-nickel alloy than just a single monolayer. Electrochemical techniques, such as potentiodynamic polarization and electrochemical impedance spectroscopy, were used to determine the protective properties of the stearic acids films. Sum frequency generation spectroscopy, atomic force microscopy, contact angle measurements and ellipsometry were used to evaluate structural properties and thickness of the surface layers. It was found that the increase of corrosion protection from mono-to multilayer films depends on the number of layers that are formed but also on their homogeneity.
