Fabrication of self-assembled monolayers

摘要

A self-assembled monolayer (SAM) is fabricated using either a semi-fluorinated sulphur containing compound, or a sem-fluorinated silane derivative and compressed carbon dioxide (CO2) as the solvent medium. The temperature and/or pressure of the compressed CO2 may be varied during the fabrication process to improve the molecular packing density of the monolayer. By using compressed CO2 as the solvent medium, monolayers with good molecular packing density can be fabricated relatively quickly without the use of environmentally unfriendly solvents.
