Fabrication of Patterned Polymer Brushes on Chemically Active Surfaces by in situ Hydrogen‐Bond‐Mediated Attachment of an Initiator

Patterned polymer brushes on carboxyl-terminated self-assembled monolayers, and patterned graft/block copolymer brushes on carboxyl- containing polymer brush layers, are fabricated. In situ hydrogen-bond formation between the hydrolyzed trichloro species of the initiator molecules and the COOH–functionalized surface yields the patterned, surface-confined initiator, and the pattern is amplified into a polymer brush by atom transfer radical polymerization.
