ABSTRACT:
A method of forming a thin film of amphiphilic molecules on a substrate by using a resealable vial carrier is provided. The method includes placing the substrate in a vacuum chamber. A resealable cap member of the vial carrier is opened. The vial carrier may contain a liquid or solid amphiphilic material. The open vial carrier is placed within the chamber. The chamber is sealed and a pressure from about 2×10+2to 5×10−6torr is applied to the chamber. The vial carrier is heated to a temperature between 100-350° C. The amphiphilic material is vaporized in the chamber. A thin film of amphiphilic molecules is formed on the substrate. The chamber is opened and the substrate having the thin film of amphiphilic molecules thereon is removed. The resealable vial carrier includes a temperature resilient vial carrier and a resealable member selectively disposed about an opening of the vial carrier. The vial carrier contains a heat vaporizable amphiphilic material for direct use in forming a thin film coating on a substrate in a vacuum chamber.
