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

    Författare :Jörgen Jansson; Fysikalisk kemi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 25. Morphology of Polymers - Development of Electron Microscopy Methods

    Författare :Helen Hassander; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SEM; TEM; polymer; electron microscopy; Polymer technology; biopolymers; Polymerteknik;

    Sammanfattning : Most polymeric materials used today are not simple homopolymers, but consist of more than one polymer, which lead to morphologies of different length scale and shape. It is important to receive knowledge of the morphologies because the properties of the materials change depending on the structure. LÄS MER
