  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. Polymers in Aqueous Lubrication

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Junxue An; KTH.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lubrication; boundary lubrication; friction; surface forces; adsorption; adsorption hysteresis; non-equilibrium state; diblock copolymer; polyelectrolyte; thermoresponsive; mucin; QCM-D; ellipsometry; AFM; Kemi; Chemistry;

    Abstract : The main objective of this thesis work was to gain understanding of the layer properties and polymer structures that were able to aid lubrication in aqueous media. To this end, three types of polyelectrolytes: a diblock copolymer, a train-of-brushes and two brush-with-anchor mucins have been utilized. READ MORE

  4. 4. Surface Force and Friction effects of adsorbed layers and surface topography

    University dissertation from Stockholm : KTH Royal Institute of Technology
