FORMATION OF SELF-ASSEMBLED MONOLAYERS

摘要

PROBLEM TO BE SOLVED: To provide a method for forming self-assembled monolayers(SAM) on a substrate, and products having this sort of monolayers. SOLUTION: The self-assembled monolayers(SAM) are formed by using a compound containing semi-fluorinated sulfur or derivatives of semi-fluorinated silane, and compressed carbon dioxide(CO2 ) as a solvent. The molecule packing density of the monolayers is improved by changing temperature and/or pressure of the compressed CO2 during the formation. By employing the compressed CO2 as the solvent, the monolayers with superior molecule packing density are formed comparatively rapidly, without employing an unfavorable solvent for the environment.
