Modification of substrate surfaces with polymer coatings

摘要

A process for forming a polymer film on a substrate through an intermediate organometallic layer is disclosed. A self-assembled monolayer (SAM) containing an initiator for living polymerization such as controlled radical polymerization is formed on the organometallic layer followed by living polymerization such as controlled radical polymerization of a polymerizable monomer component.

1. A process for forming a polymer film on a substrate surface comprising:
(a) contacting the substrate surface through an intermediate organometallic layer 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 reactive with the organometallic layer to bond the organophosphorus acid to the substrate surface and with the initiator extending outwardly from the substrate surface, (c) contacting the SAM with a living polymerizable monomer component comprising a living polymerization catalyst, and (d) polymerizing the monomer component with the initiator to form a polymer layer.
