Abstract
A process for forming a fluorocarbon polymer film on a substrate is disclosed. A self-assembled monolayer (SAM) containing an initiator for living polymerization such as controlled radical polymerization is formed on the surface of the substrate followed by living polymerization such as controlled radical polymerization of a polymerizable fluorocarbon monomer component.
Claims22
A process for forming a fluorocarbon-containing polymer film on a substrate surface comprising:
- (a) contacting the substrate surface with an organophosphorus acid containing in a terminal portion a phosphorus acid group, and in a second terminal portion, an initiator for living polymerization,
- (b) forming a self-assembled monolayer (SAM) from the compound with the phosphorus acid group being adsorbed on the substrate surface and with the initiator extending outwardly from the substrate surface,
- (c) contacting the SAM with a radically polymerizable monomer component comprising at least in part a fluorocarbon-containing monomer and a living polymerization catalyst, and
- (d) polymerizing the monomer component with the initiator to foim a layer of fluorocarbon-containing polymer.
