  1. 1. Scattering Studies of Macromolecules in Solution

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

    Abstract : 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. READ MORE

  2. 2. Structural Changes in Nonionic Surfactant Systems

    Author : Sanja Bulut; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vesicles; Nonionic Surfactant; Wormlike Micelles; Lamellar Phase; NMR; MRI; SLS; DLS; cryo-fracture-TEM; centrifugation; cryo-TEM;

    Abstract : In this thesis we have studied structural changes of a nonionic surfactant self-assembly, as governed by changes in temperature and concentration. The techniques used in experimental investigations were dynamic and static light scattering, nuclear magnetic resonance and cryo-transmission electron microscopy (using a novel specimen preparation protocol).

  3. 3. The Interaction between Triblock Copolymers and Surfactants in Dilute Aqueous Solution

    Author : Jörgen Jansson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; Physical chemistry; Fysikalisk kemi; Calorimetry; SAXS; DLS; SLS; Light scattering; Structure; Complex; Block copolymer-surfactant interaction; Block copolymer vesicles; Self-assembly; Triblock copolymers; NMR;

    Abstract : The solution properties of dilute aqueous solutions of poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers and their interaction with surfactants have been investigated using static and dynamic light scattering, combined with small angle X-ray scattering, calorimetry and nuclear magnetic resonance techniques. In aqueous solution, the triblock copolymers P123 and F127 (EO20PO68EO20 and EO97PO68EO97, respectively) form micelles with a PPO core and a PEO corona. READ MORE
