Methods for self-assembling monolayers to mitigate hydrogen permeation

Abstract

The presently disclosed methods provide for preparing a stable hydrophobic self-assembled monolayer (SAM) coating, that includes preparing a SAM solution by combining a SAM compound with an initial solvent and an additional solvent and mixing, in a sealed container, the SAM solution at a first fixed temperature at a constant rotational speed for a first fixed time interval. The SAM coating is then prepared by treating a substrate to achieve pristine state, and heating the substrate at a second fixed temperature for a second fixed time interval. Then within a sealed container, immersing the substrate in the SAM solution for a third fixed time interval. Following the completion of the third fixed time interval, the substrate is removed from the sealed container and treated with the initial solvent and the additional solvent to remove excess SAM material, and heated at a third fixed temperature.
