  1. 1. Block Copolymer Electrolytes Polymers for Solid-State Lithium Batteries

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Andreas Bergfelt; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The use of solid polymer electrolytes (SPEs) for lithium battery devices is a rapidly growing research area. The liquid electrolytes that are used today are inflammable and harmful towards the battery components. READ MORE

  2. 2. Mixed Block Copolymer Solutions: Self-Assembly and Interactions

    University dissertation from Lund University, Faculty of Science, Department of Chemistry, Division of Physical Chemistry

    Author : Solmaz Bayati; Lunds universitet.; Lund University.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymer; Block Copolymer; PEO-PPO-PEO; Pluronics©; Bile Salt; NaGDC; PNIPAAM; PAMPTMA; PAMPS; Mixed Micelle; Self-Assembly; Mixed Complexes;

    Abstract : Popular Science SummaryPolymers are giant molecules consisting of a repetition of many small units (monomers) that are linked together by chemical bonds. If we consider a long necklace as a polymer chain, the beads are the monomers and the part of the thread which connects the beads together is the chemical bond. READ MORE

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

    University dissertation from Birgitta Svensson, Physical Chemistry 1, Lund University

    Author : Birgitta Svensson; Lunds universitet.; Lund University.; [1999]
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Formation of Block Copolymer and Surfactant Vesicles

    University dissertation from Karin Bryskhe, Villav. 8, 232 53 Åkarp

    Abstract : Popular Abstract in Swedish En amfifil molekyl innebär en molekyl som består av två delar, en som är hydrofil (“vattenälskande”) och en som är hydrofob (“vattenhatande”). Ofta består den amfifila molekylen av en ”vattenälskande” huvudgrupp och en ”vattenhatande” svans och kallas för surfaktant. READ MORE

  5. 5. Self-assembly in Melts of Block copolymer-based Systems Featuring Supramolecular Interactions

    University dissertation from Department of Chemistry, Lund University

    Author : Mehran Asad Ayoubi; Lunds universitet.; Lund University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hierarchical self-assembly; melt; block copolymer; cationic surfactant; non-ionic surfactant; supramolecular interactions; microphase separation; Linear-b-AmphComb;

    Abstract : Popular Abstract in English From everyday experience we know that water and oil do not mix. In the scientific language we say they phase separate from each other. This happens because a water molecule and an oil molecule are inherently incompatible, the former exhibiting a ‘polar’ character and the latter a ‘non-polar’ one. READ MORE
