  1. 1. The Rôle of Side-Chains in Polymer Electrolytes for Batteries and Fuel Cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jaanus Karo; Uppsala universitet.; Uppsala universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molecular dynamics; polymer electrolytes; side-chains; Li-ion batteries; proton exchange membrane fuel cell PEMFC ; PFSA membrane; NATURAL SCIENCES Chemistry Other chemistry; NATURVETENSKAP Kemi Övrig kemi; NATURAL SCIENCES Physics Atomic and molecular physics; NATURVETENSKAP Fysik Atom- och molekylfysik; Materialvetenskap; Materials Science;

    Abstract : The subject of this thesis relates to the design of new polymer electrolytes for battery and fuel cell applications. Classical Molecular Dynamics (MD) modelling studies are reported of the nano-structure and the local structure and dynamics for two types of polymer electrolyte host: poly(ethylene oxide) (PEO) for lithium batteries and perfluorosulfonic acid (PFSA) for polymer-based fuel cells.

  4. 4. Anionic Graft Copolymers with Poly(ethylene oxide) Side-Chains; Synthesis, Solution Properties and Ion Conduction

    University dissertation from Chemical Engineering 2, Lund University

    Author : Helene Dérand; Lund University.; Lunds universitet.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dieletric properites; ion conduction; solution properties; aggregation; amphiphilic polymers; poly ethylene oxide ; preparation; grafting; Polymer technology; biopolymers; Polymerteknik;

    Abstract : The research underlaying this thesis involves synthesis and characterization of well-defined anionic graft copolymers carrying poly(ethylene oxide) (PEO) side-chains. Two different grafting techniques were used. Backbone polymers were prepared through radical terpolymerization of maleic anhydride, styrene and an additional comonomer. READ MORE

  5. 5. Poly(phenylene oxide)s functionalized with cationic side chains: design, synthesis and properties as anion exchange membranes
