Abstract

A substrate surface is coated with a thin film by exposing the substrate to a vapor of amphiphilic molecules in a vacuum chamber, and allowing the amphiphilic molecules to spontaneously self-assemble and attach to the substrate surface wherein the substrate and a quantity of a vaporizable film forming material containing amphiphilic molecules is placed in a vacuum chamber, establishing a vacuum within said chamber, followed by vaporization of the film forming material.
