Study of the Scale Formation Mechanism on Gold Modified with an Alkanethiol Monolayer

Abstract

Scaling is a problem in many industrial processes. To control and minimize it, it is important to understand the dynamics of the scale formation. In this paper, the scale formation was examined on two kinds of gold surfaces. One was a pure metallic gold surface, and the other was a gold surface modified with an alkanethiol self-assembled monolayer. A series of surface characterization experiments were performed to ensure a good understanding of the gold-thiol bond stability in a caustic solution.

Self-Assembled Monolayers ofn-Dodecanethiol on Nickel Surfaces Using 2-Hydroxyethylammonium Formate as Reducing Medium

“…[1][2][3][4] A major research focus of this method is the self-assembly of thiol derivatives, in particular organothiols, on different metals such as gold, silver, copper, platinum, palladium, GaAs etc. [5][6][7][8][9][10][11] Even though gold is largely considered as metal substrate for monolayer elaboration due to its inertness, good conductivity and high affinity for sulfur, self-assembled monolayers (SAMs) on other metals such as Ni, Co and Fe also have many interesting properties and applications. [12][13][14][15] For instance, Ni thiol molecular junctions can be used in spintronics and semiconductor devices.…”
