Polymer brushes are the assemblies of the macromolecular chains tethered to surfaces or interfaces. Current methods of advanced polymer synthesis and surface functionalization techniques allow controlling the morphological structure of the polymer brushes to create the smart surfaces with the adaptive or responsive properties. Block copolymers, which consist of covalently connected, chemically distinct macromolecular blocks, can be attached to the surfaces to form the brushes. Unique morphologies that are different from those in their bulk states can be obtained due to competing organizing energies in the block copolymer/surface system. These include the chemical affinities between polymer blocks or between polymers and surface, and the ordering energy of the polymer chains. In this regard, we will discuss recent progress in the research on the block copolymer brushes including our studies on the nanopatterned polymer brushes obtained from the rod-coil block copolymers. |
