  1. 1. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure

    Författare :Birgitta Svensson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical chemistry; lyotropic; thermotropic; SANS; SAXS; scattering; semicrystalline; reverse micelle; micellar solution; liquid crystalline; phase diagram; phase behaviour; block copolymer; pluronic; poly ethylene oxide ; poly propylene oxide ; quantum chemistry; Teoretisk kemi; kvantkemi;

    Sammanfattning : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. LÄS MER

    Sammanfattning : Knowledge about structure and dynamics of the important biological macromolecules — proteins, nucleic acids, lipids and sugars — helps to understand their function. Atomic-resolution structures of macromolecules are routinely captured with X-ray crystallography and other techniques. LÄS MER

  4. 3. Aqueous Block Copolymer Systems. Self-association, Phase Behaviour and Partitioning of Biomolecules

    Författare :Mårten Svensson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; block copolymer self-association partitioning phase behaviour; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The phase and partitioning behaviour of aqueous block copolymer systems has been studied. The block copolymers used in this work were built up of three blocks. The middle block was poly(propylene oxide) (PPO) and hydrophobic. The two outer blocks constisted of poly(ethylene oxide) (PEO) chains and less hydrophobic. LÄS MER
