Patent ID: 7405034

Claim:
A method for making a polymeric structure on a substrate, comprising: providing a substrate; functionalizing at least a portion of the substrate in a one-step process with a silane perfluorophenylazide or a disulfide perfluorophenylazide to provide a silane-perfluorophenylazide or disulfide-perfluorophenylazide functionalized surface substantially devoid of unreacted amino groups; applying a first polymeric material to the silane-perfluorophenylazide or disulfide-perfluorophenylazide functionalized surface of the substrate; exposing the first polymeric material to a reaction energy source in a pre-determined pattern to covalently bond a layer of the first polymeric material to the substrate in the pre-determined pattern; removing unbound first polymeric material from unexposed areas of the substrate surface; applying a second polymeric material to the surface of the substrate so the second polymeric material occupies at least a portion of the surface of the substrate not occupied by the first polymeric material, wherein the second polymeric material is not formed by a reaction of the first polymeric material; and exposing the second polymeric material to a reaction energy source to covalently bond a layer of the second polymeric material to the substrate, the first and second polymeric materials forming a microstructure defined by the first and second polymeric materials.
