  2. 1. Ternary Block Copolymer - Water - "Oil" Systems: Effects of "Oil" Type and Block Size on Phase Behaviour and Structure

    Author : Peter Holmqvist; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; poly propylene oxide ; poly ethylene oxide ; poloxamer; micelles; lyotropic liquid crystals; SAXS; structure; phase behavior; self-assembly; block copolymers; amphiphiles; poly tetrahydrofurane ; Physical chemistry; Fysikalisk kemi;

    Abstract : It has recently been established in our group that amphiphilic block copolymers consisting of a hydrophilic and a hydrophobic part can self-assemble in the presence of selective solvents (“water” and “oil”) into a variety of different solution and lyotropic liquid crystalline microstructures. The effects of the “oil” type, hydrophilic block size and hydrophobic block type on the phase behavior and microstructure of ternary isothermal copolymer - oil - water systems have been addressed in this thesis.

  4. 2. Adsorption Properties of Triblock Copolymers at Solid Surfaces

    Author : Krister Eskilsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; Ellipsomery; Surface force; Adsorption; Triblock Copolymer;

    Abstract : The interfacial behaviour of nonionic triblock copolymers of the type poly(ethylene oxide-tetrahydrofurane-ethylene oxide) has been systematically examined at different types of surfaces. It is shown how the chemical nature of the substrate greatly influences the adsorption behaviour of block copolymers. READ MORE
