    Notes: Abstract. We have used atomic force microscopy to study the adsorption of PolyStyrene-Poly(VinylPyridine) (PS-PVP) block copolymers from a selective solvent onto atomically smooth mica surfaces. At certain copolymer concentrations, we observe a highly regular array of spherical surface micelles covering macroscopic areas of the substrate surface. Evidence is given for a thin homogeneous layer underneath the micelles which is probably due to adsorption of free copolymer chains and brush formation prior to the formation of the micellar structures. We discuss the quality of the self-assembled structures regarding different types of defects and try to identify means for improving the long range periodicity of the structures.

    Chemically functionalized surfaces from ultrathin block-copolymer films (1996)
    [S.l.] : American Institute of Physics (AIP)

    Notes: Supramolecular self-assembly of polystyrene–poly(vinylpyridine) diblock copolymers adsorbed from a selective solvent onto smooth substrates was used to create surfaces with regularly varying chemical composition. Well-ordered arrays of localized chemical reaction sites are formed on such surfaces with sizes and intersite distances of molecular length scales. We demonstrate site-specific complex formation with transition metal salts resulting in a nanoscopic ordered array of metal salt–polymer complexes. Selective etching of the metal-loaded microdomains is shown. The effect of block copolymer molecular architecture on the supramolecular structure of these "chemically functionalized'' surfaces was studied. © 1996 American Institute of Physics.
