  4. 23. Self-assembly in Melts of Block copolymer-based Systems Featuring Supramolecular Interactions

    Författare :Mehran Asad Ayoubi; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hierarchical self-assembly; melt; block copolymer; cationic surfactant; non-ionic surfactant; supramolecular interactions; microphase separation; Linear-b-AmphComb;

    Sammanfattning : The subject of this thesis is experimental investigation of self-assembly in solvent-free (ionic) macromolecular systems that contain block copolymer chains as the basic constituent component in combination with low molecular weight amphiphiles. In particular, especial attention is paid to study thoroughly a new class of block copolymer-based ionic supramolecules, named as Linear-b-AmphComb, that feature novel hierarchical self-assembly characteristics.

  5. 24. Mass Transport Properties in Supramolecular Systems Studied by Diffusion and Relaxation NMR

    Författare :Patrik Jarvoll Dae; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NMR; T2; diffusion; hydrogel; exchange dynamics; T1; magnetic susceptibility; organosilica nanoparticles; microstructure; relaxation; supramolecular systems;

    Sammanfattning : This thesis shows how diffusion and relaxation NMR can be applied in various aspects to study mass transport in supramolecular systems. Information about these systems can be obtained, either by direct measurement of the molecules that are incorporated in a supramolecular structure, or via probe molecules, which indirectly gives information about the system.
