Voets, Ilja K. Keizer, Arie de Leermakers, Frans A.M. Debuigne, Antoine Jérôme, Robert Detrembleur, Christophe Cohen Stuart, Martien A. 2009-06-30 The formation of spherical micelles in aqueous solutions of poly(<i>N</i>-methyl-2-vinyl pyridinium iodide)-<i>block</i>-poly(ethylene oxide), P2MVP-<i>b</i>-PEO and poly(acrylic acid)-<i>block</i>-poly(vinyl alcohol), PAA-<i>b</i>-PVOH has been investigated with light scattering-titrations, dynamic and static light scattering, and ¹H 2D Nuclear Overhauser Effect Spectroscopy. Complex coacervate core micelles, also called PIC micelles, block ionomer complexes, and interpolyelectrolyte complexes, are formed in thermodynamic equilibrium under charge neutral conditions (pH 8, 1 mM NaNO₃, <i>T </i>= 25 °C) through electrostatic interaction between the core-forming P2MVP and PAA blocks. 2D ¹H NOESY NMR experiments show no cross-correlations between PEO and PVOH blocks, indicating their segregation in the micellar corona. Self-consistent field calculations support the conclusion that these C3Ms are likely to resemble a ‘patched micelle’; that is, micelles featuring a ‘spheres-on-sphere’ morphology. application/pdf https://folia.unifr.ch/global/documents/301620 https://folia.unifr.ch/documents/301620/files/voe_ehc.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1016/j.eurpolymj.2009.06.020 info:eu-repo/semantics/openAccess License undefined European Polymer Journal. - 2009, vol. 45, no. 10, p. 2913-2925 Block-copolymers Micelles Polyion complex micelles Complex coacervation Self-assembly Polyelectrolyte info:eu-repo/classification/udc/53 Electrostatic hierarchical co-assembly in aqueous solutions of two oppositely charged double hydrophilic diblock copolymers http://purl.org/coar/resource_type/c_6501
