Self-Assembly of Nanoparticle,Copolymer Mixtures: A Kinetic Point of View,

ADVANCED MATERIALS, Issue 3 2007
J. He
The prediction of synergistic effects between two self-organizing systems is tested. In,situ grazing-incidence small-angle X-ray scattering (see figure) is used during thermal annealing of a nanoparticle,copolymer mixture, and shows that the orientation of the microdomains begins at the free surface and propagates in the film towards the substrate. This synergistic interaction is shown to apply to both cylindrical and lamellar block-copolymer morphologies. [source]

Hydrogen bond-mediated self-assembly and supramolecular structures of diblock copolymer mixtures

POLYMER INTERNATIONAL, Issue 5 2009
Shiao-Wei Kuo
Abstract This review summarizes recent advances in the preparation of hydrogen bonding block copolymer mixtures and the supramolecular structures they form through multiple hydrogen bonding interactions. Hydrogen bonding in block copolymer mixtures that form nanostructures and have unusual electronic, photonic and magnetic properties is a topic of great interest in polymer science. Combining the self-assembly of block copolymers with supramolecular structures offers unique possibilities to create new materials with tunable and responsive properties. The self-assembly of structures from diblock copolymer mixtures in the bulk state is readily controlled by varying the weight fraction of the block copolymer mixture and the copolymer composition; in solution, the morphologies are dependent on the copolymer composition, the copolymer concentration, the nature of the common solvent, the amount of the selective solvent and, most importantly, the hydrogen bonding strength.
