    Author : Solmaz Bayati; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer; Block Copolymer; PEO-PPO-PEO; Pluronics©; Bile Salt; NaGDC; PNIPAAM; PAMPTMA; PAMPS; Mixed Micelle; Self-Assembly; Mixed Complexes;

    Abstract : This thesis incorporates studies on the aqueous systems of two types of thermoresponsive amphiphilic block copolymers; a series of nonionic triblock copolymers comprising blocks of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) denoted as PEO-PPO-PEO block copolymers, and a series of ionic diblock copolymers consisting of one charged block and one block of poly(N-isopropylacrylamide) (PNIPAAM). Various techniques, such as dynamic and static light scattering (DLS and SLS), small angle X-ray and neutron scattering (SAXS and SANS), high sensitivity differential scanning calorimetry (HSDSC), turbidimetry, electrophoretic mobility measurements, and two-dimensional proton NMR nuclear Overhauser effect spectroscopy (2D 1H NMR NOESY), were applied to study these block copolymer systems.
