Abstract
The present invention relates to 'grafting to' methods of modifying materials surfaces with high-density polymer brushes. A method of the present invention comprises contacting in succession or simultaneously an activated material surface, a solution of a polymeric material having a polymeric backbone with pendant reactive moieties, and a melt of brush-forming terminally-functionalized polymer chains, in order to allow a covalent bonding reaction to occur between surface and polymers, wherein upon completion of the reaction, the polymeric material forms a layer between the material surface and the brush polymer chains.
