Vapor deposited functional organic coatings deposited on a halogen-containing substrate
First Claim
1. A method of depositing an organic coating on a substrate from a vapor phase organic-comprising precursor, wherein said substrate surface upon which said organic coating is applied is a halogenated surface produced by treatment of said substrate with a vaporous, halogen-containing compound in a process chamber under vacuum conditions ranging from about 1 mTorr to about 10 Torr, at a temperature ranging from about 25°
- C. to about 100°
C., wherein said organic-comprising precursor contains at least one nucleophilic functional group which reacts with said halogenated surface to attach an organic coating to said surface, and wherein said organic-comprising precursor is charged to said processing chamber in measured quantities using batch-like charging procedures, whereby a particularly uniform growth of the coating on the surface is achieved.

Abstract
We have developed an improved vapor-phase deposition method and apparatus for the attachment of organic films/coatings containing a variety of functional groups on halogen-containing substrates. The substrate surface is halogenated using a vaporous halogen-containing compound, followed by a reaction with at least one organic molecule containing at least one nucleophilic functional group. Halogenation of the substrate surface and subsequent reaction with the organic molecule are carried out in the same process chamber in a manner such that the halogenated substrate surface does not lose its functionality prior to reaction with the nucleophilic functional group(s) on the organic molecule.
