  4. 3. Scattering Studies of Macromolecules in Solution

    Författare :David Löf; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bacteriophage lambda; Dynamic Light Scattering; Time-Resolved; Mixed Micelles; Nonionic Surfactant; Triblock Copolymer; Calorimetry; SLS; Rheology; DLS; SAXS;

    Sammanfattning : The sphere-to-rod transition of nonionic micelles of the PEO-PPO-PEO triblock copolymer P123 and the surfactant C12EO6 was studied using dynamic and static light scattering, small angel X-ray scattering, rheology and calorimetry. The transition temperature was dependent of the C12EO6/P123 molar ratio, which means that a larger content of C12EO6 yields a higher transition temperature. LÄS MER
